Co-managed IT services for Canadian businesses with internal IT teams
Co-managed engagements pair a client’s in-house IT team with an external security partner. For the security-side of that pairing, see our 2026 guide to what an MSSP (managed security service provider) is: 24/7 SOC, vulnerability management, compliance reporting, vCISO advisory under one contract.
Fusion Computing is a Canadian co-managed IT services provider delivering augmented IT support from three regional offices in Toronto, Hamilton, and Metro Vancouver, with remote coverage across Ontario, British Columbia, and the rest of Canada. We work alongside your internal IT team rather than replacing them.

What co-managed IT actually means
Co-managed IT services supplement your existing internal IT team with 24/7 NOC monitoring, advanced cybersecurity tooling, Tier 3 escalation, vCIO strategic planning, and surge capacity. Fusion Computing fills the gaps your internal team cannot cover alone. Your IT lead keeps ownership of the technology roadmap, the help desk, and the vendor relationships. We take the pieces that require 24/7 staffing, specialized security expertise, and senior-level escalation depth that a 1-to-5 person team cannot sustain on its own.
According to 2024 MSP industry research, co-managed IT is the fastest-growing segment in Canadian IT services, up 41% year-over-year as internal IT teams face cybersecurity workloads that exceed their bench strength.
According to Statistics Canada’s 2025 Canadian Survey of Cyber Security and Cybercrime, 43% of Canadian organizations were targeted by a cyber attack in the previous 12 months. Most internal IT teams lack the 24/7 coverage required to respond in time.
According to the Canadian Centre for Cyber Security, ransomware attacks now typically move from initial access to full impact in under 24 hours, faster than most internal IT teams can detect without supplemental managed detection and response.
IBM’s 2024 Cost of a Data Breach report found organizations with integrated security operations between internal and external teams contained breaches 74 days faster than peers operating in siloes.
“Co-managed IT is where most Canadian SMBs with internal IT should sit: retain the IT lead who knows the business, layer on the CISSP-led security controls, 24/7 NOC monitoring, and specialist skills you cannot justify hiring for. Two teams, one accountability chain, and the internal lead stays senior.” – Mike Pearlstein, CISSP, CEO, Fusion Computing
The real pressures on a 1–5 person internal IT team
Internal IT teams in Canadian SMBs are exceptional at day-to-day operations. The problem is structural, not a skills gap. A small team cannot be in three places at once, and the workload has grown beyond what any one person or small group can absorb.
Alert fatigue
Hundreds of alerts, no triage capacity
Enterprise-grade EDR and RMM tools generate hundreds of alerts per day. Without a dedicated analyst, genuine threats get buried under noise. A 2024 Sophos study found 71% of IT teams report being overwhelmed by the volume of security alerts their tools generate.
After-hours gaps
Breaches happen at 2am on Fridays
The Canadian Centre for Cyber Security notes that ransomware actors deliberately time their lateral-movement and detonation phases for evenings and weekends when IT coverage is thinnest. A single IT generalist cannot maintain genuine 24/7 watch without burning out.
No security depth
Helpdesk generalists vs. CISSP-level threats
Most internal IT professionals are strong generalists, excellent at Microsoft 365, laptops, user onboarding, and network administration. Active threat hunting, EDR tuning, CIS Controls v8.1 hardening, and incident-response runbook management are a different discipline entirely.
Vacation coverage
One person out means zero coverage
When your IT manager takes a two-week vacation, patches drift, alerts go unreviewed, and a critical server issue becomes a crisis with no one to call. Co-managed IT functions as a permanent backup that eliminates single-person coverage risk.
Reactive mode only
Ticket queue crowds out strategy
An IT manager drowning in tickets cannot also produce a three-year technology roadmap, evaluate cloud migration costs, prepare compliance documentation, or run quarterly security reviews. Fusion’s vCIO layer gives your team that strategic capacity back.
IT burnout
The retention risk nobody talks about
A 2024 TechRepublic survey found 62% of IT professionals in teams of five or fewer reported moderate-to-severe burnout, with after-hours incident response as the top driver. When your IT manager leaves, institutional knowledge walks out with them. Co-managed IT reduces that pressure and the retention risk it creates.
The structural gap co-managed IT fills
A small internal IT team is designed to run the business, not to simultaneously staff a 24/7 security operations centre, maintain Tier 3 escalation depth, and deliver quarterly vCIO advisory. Co-managed IT does not replace your team. It fills the three operating gaps that a small team structurally cannot cover: continuous monitoring, security operations expertise, and strategic advisory capacity.
Co-managed IT vs. fully managed IT: which model fits your business
The right model depends on whether you have internal IT staff. If you do, co-managed preserves their ownership while filling the gaps they cannot cover. If you do not, fully managed means Fusion becomes your entire IT department.
| Factor | Co-Managed IT | Fully Managed IT |
|---|---|---|
| Who needs this | Businesses with 1–5 person IT team | Businesses with no internal IT staff |
| Help desk ownership | Your internal team owns Tier 1/2 | Fusion owns all tiers |
| NOC/SOC monitoring | Fusion provides 24/7 via NinjaOne | Fusion provides 24/7 via NinjaOne |
| Security operations | Fusion: Huntress + SentinelOne + CISSP lead | Fusion: Huntress + SentinelOne + CISSP lead |
| Technology roadmap | Your IT lead owns, Fusion advises via vCIO | Fusion owns as virtual IT department |
| Vendor relationships | Your team keeps existing relationships | Fusion manages all vendor contracts |
| Institutional knowledge | Internal team retains full context | Fusion documents from scratch |
| Escalation path | Internal IT → Fusion Tier 2/3 | Fusion Tier 1 → 2 → 3 |
| Pricing per user/month | From $130 (scope-dependent) | $180–$250 (full stack) |
| User range | 30–300 users | 10–200 users |

What Fusion provides in a co-managed engagement
These are the operating responsibilities Fusion takes on. Your internal team keeps the help desk, user management, and institutional knowledge. Fusion fills the parts that require 24/7 staffing, security-operations expertise, and senior-level depth.
24/7 NOC Monitoring
Fusion watches your servers, endpoints, network, and cloud workloads around the clock using NinjaOne RMM. Alerts route to our NOC team 24/7/365. Your IT manager stops being the single point of failure for after-hours response.
Tools: NinjaOne RMM · Automated alert triage · Escalation runbooks
Security Operations (SOC)
CISSP-certified lead manages your entire security stack. Huntress EDR for managed detection and response, SentinelOne XDR for endpoint behavioural analysis, Fortinet firewall management, and CIS Controls v8.1 alignment. Active threat hunting and security awareness training included.
Tools: Huntress EDR · SentinelOne XDR · Fortinet · KeeperSec
Tier 3 Escalation
When your internal team hits a wall on a complex infrastructure problem, security incident, or advanced server issue, they escalate to Fusion’s senior engineers. Documented escalation paths via ConnectWise PSA ensure the handoff is clean and your team sees full ticket history in one system.
Tools: ConnectWise Manage PSA · Documented escalation scripts
vCIO Strategic Sessions
Quarterly business reviews with Fusion’s virtual CIO give your leadership team a technology roadmap, budget forecast, compliance summary, and risk posture review. Your IT manager stops being the sole source of strategic IT advice and gains a senior partner to present alongside.
Cadence: Quarterly reviews · Annual roadmap · Budget modelling
Patch Management Backup
Fusion manages patch cycles for operating systems, third-party applications, and firmware when your team is behind, on vacation, or stretched across a project. Patch compliance reporting is included in the monthly service review so you always know where the estate stands.
Scope: OS patching · Third-party apps · Firmware · Compliance reporting
Compliance Documentation
Fusion maintains the documentation your auditors, insurers, and compliance frameworks require: asset inventories, risk registers, incident-response runbooks, access control reviews, and security-awareness training records. Aligned to OSFI, PHIPA, PIPEDA, and SOC 2 audit prep requirements.
Frameworks: OSFI · PHIPA · PIPEDA · CIS Controls v8.1 · SOC 2
What your internal IT team keeps
Co-managed IT is not a takeover. The responsibilities below stay with your team by design. Fusion does not insert itself into your day-to-day operations, your vendor relationships, or your team’s decision authority.
Help desk ownership
Your team owns Tier 1 and Tier 2 help desk operations. User tickets, password resets, onboarding, device setup, and day-to-day user requests stay with the people who know your business.
Institutional knowledge
Your IT team knows which systems are quirky, which users need extra support, and how the business runs. That context stays internal. Fusion supplements it, never supplants it.
Vendor relationships
Microsoft, your ISP, line-of-business application vendors, and hardware suppliers. Your team keeps those relationships and those contracts. Fusion does not insert itself as a mandatory intermediary.
Day-to-day user management
New hire setups, account provisioning, application access, and internal training stay with your team. You remain the face of IT to your employees.
Project delivery
Your IT lead owns the project backlog, office moves, Microsoft 365 migrations, and hardware refresh cycles. Fusion can assist on individual projects as a subcontractor, but project ownership stays with your team unless explicitly agreed otherwise.
Decision authority
Technology decisions belong to your IT lead and leadership team. Fusion advises via the vCIO relationship, but every purchasing decision, architectural choice, and priority call is yours to make.
How co-managed onboarding works: three steps, zero disruption
The co-managed onboarding process is designed around your existing tools, your existing workflows, and your existing team structure. Nothing changes on day one for your users.
Documentation audit (Week 1–2)
A Fusion senior engineer and your IT lead run a structured documentation audit together. We map every system, every tool already in your stack, every vendor contract, and every escalation point. The output is a shared knowledge base in IT Glue (or your existing documentation platform) that both teams can access.
This audit produces the written responsibility matrix: a clear, signed-off document that states who owns every operational domain. No ambiguity. No overlap. No gaps.
Tool integration (Week 3–4)
If you already run NinjaOne RMM, ConnectWise PSA, Datto BCDR, or another standard stack, Fusion works inside your existing tools. We do not force a tool migration. If you need additional tooling for the security layer (Huntress EDR, SentinelOne XDR), those are layered on top of what you have without replacing it.
The monitoring configuration, alert routing, and escalation-path logic are all tested before going live. Your team reviews and approves every routing rule before the NOC begins watching.
Handshake protocols (Week 5 onwards)
The handshake protocols govern how work moves between your team and Fusion in real time. Which ticket types escalate automatically, which require a call from your IT lead first, how security alerts are communicated, and who gets paged at what severity threshold. All documented, tested with a tabletop exercise, and agreed by both teams before going live.
From week five, the engagement is fully operational. Your named account lead schedules the first monthly review, and the quarterly vCIO review is calendared for 90 days in.
Onboarding timeline
Five weeks from signed agreement to fully operational co-managed engagement. Week 1–2: documentation audit and responsibility matrix. Week 3–4: tool integration and monitoring configuration. Week 5+: handshake protocols live, NOC watching, first monthly review scheduled. No user disruption throughout.
Why Fusion Computing is Canada’s co-managed IT provider for SMBs with internal teams
Fusion has delivered co-managed engagements since 2012. About one in three of our clients use this model. Here is what makes Fusion the right co-managed IT provider for a Canadian business with an internal IT team.
As a Canadian co-managed IT provider, Fusion operates from Toronto, Hamilton, and Metro Vancouver with nationwide remote coverage. All client data is processed and stored in Canada, a requirement for regulated industries in Ontario and British Columbia. CISSP-certified security leadership is assigned to every account, not just enterprise-tier clients.
CISSP
Certified security leadership on every account
Most co-managed providers assign a help-desk account manager. Fusion assigns a CISSP-certified lead. That distinction matters when you need someone who can read an EDR alert, brief your executive team on a security incident, and sign off on compliance documentation.
4:1
Tech-to-client ratio vs. industry average of 12:1
The industry average MSP runs 12 clients per technician. Fusion runs 4:1. That ratio is the structural reason our response times hold up and why your escalations get handled by an engineer who knows your environment, not a generalist reading documentation for the first time.
Canadian
Data residency and sovereignty throughout
All client data processed and stored in Canada. For regulated industries (financial services, healthcare, legal, professional services), this is a compliance requirement that matters from day one. Fusion has operated as a Canadian-owned MSP since 2012.
93%
First-contact resolution rate
93% of issues resolved on first contact. In co-managed, this matters because Fusion handles your most complex escalations. A low FCR from your co-managed partner creates more work for your internal team, not less.
Named
Account lead who knows your environment
Every co-managed client has a named account lead who attends every review, knows your environment, and serves as the single point of contact for your IT manager. No ticket queues, no rotating agents reading your documentation for the first time.
SOC 2
Aligned security operations practices
Fusion’s security operations are aligned to SOC 2 Trust Services Criteria covering security, availability, and confidentiality. When your cyber insurer or auditor asks about your co-managed partner’s security posture, Fusion provides the documentation they need.

How co-managed IT supports OSFI, PHIPA, and SOC 2 audit prep
Regulated industries in Canada face compliance requirements that go beyond what a small internal IT team can document and maintain on its own. Co-managed IT with Fusion layers a CISSP-led compliance program on top of your internal team’s operational knowledge.
OSFI B-13 (financial services)
Technology and cyber risk management
Fusion’s co-managed security program supports OSFI B-13 requirements for federally regulated financial institutions, including third-party risk management documentation, incident-response testing, and continuous control monitoring. Co-managed documentation packages include the audit artefacts your B-13 assessor will request.
PHIPA (healthcare)
Personal health information protection
For Ontario healthcare providers and their business associates, PHIPA requires that personal health information is handled under safeguards that include technical, administrative, and physical controls. Fusion’s co-managed program covers the technical controls: encryption, access governance, audit logging, and breach-detection capabilities.
SOC 2 audit prep
Trust Services Criteria readiness
If your business is pursuing SOC 2 Type I or Type II certification, or if enterprise clients are requiring it as a vendor prerequisite, Fusion’s co-managed engagement produces the evidence set your auditor needs: change management logs, access review records, patch compliance reports, security awareness training completion, and incident-response documentation.
PIPEDA & Bill C-27
Privacy breach response and reporting
Canada’s privacy law requires breach notification to the OPC when there is a real risk of significant harm. Fusion’s co-managed incident-response runbooks include the breach-classification and reporting workflows your privacy officer needs to meet the 30-day notification requirement under PIPEDA Breach Regulations.
Canadian regulatory context: Statistics Canada reports that 97.9% of Canadian employer businesses are small or medium sized, and most run with one or two internal IT staff who cannot realistically cover 24×7 incident response on their own. The Canadian Centre for Cyber Security puts ransomware as the top cyber threat to Canadian organizations, with SMBs disproportionately targeted due to thin staffing and weak after-hours coverage. ISED data on digital adoption shows internal IT teams are stretched across cloud migration, Microsoft 365 governance, and compliance work simultaneously, which is exactly the gap a co-managed model fills. Sources: statcan.gc.ca, cyber.gc.ca, ised-isde.canada.ca.
Co-managed IT pricing
Co-managed IT starts from $130/user/month. Because your internal team absorbs Tier 1 and Tier 2 help desk, the scope Fusion covers is narrower than a fully managed engagement, which is why the price is lower. Final pricing is custom based on user count, scope of Fusion coverage, and number of locations.
Co-Managed
From $130
per user / month
- ✓ 24/7 NOC monitoring
- ✓ CISSP-led SOC security overlay
- ✓ Tier 3 escalation
- ✓ vCIO quarterly reviews

Who co-managed IT services in Canada are for
Co-managed IT works best when you already have internal IT staff who are excellent at the day-to-day but need backup on the pieces that require 24/7 staffing and senior security expertise. If any of the points below describe your situation, co-managed is worth a conversation.
You have 1–5 IT staff serving 30–300 users
The team is capable but structurally thin. Security, after-hours coverage, and Tier 3 escalation require depth that a small team cannot sustain alone.
Your IT manager is a strong generalist but not a security specialist
Excellent at Microsoft 365, user support, and infrastructure. Not resourced for EDR tuning, CIS Controls hardening, and active threat hunting.
You need after-hours and vacation coverage without hiring a second shift
A 2am server outage or Friday evening ransomware detection should not depend on your IT manager being available. Fusion’s NOC covers the gaps.
You operate in a regulated industry (financial, healthcare, legal, professional services)
OSFI, PHIPA, PIPEDA, or SOC 2 requirements need documented controls and audit artefacts your internal team cannot maintain on their own.
You are growing and your IT team cannot scale with the business
Going from 50 to 120 users in two years stresses a small IT team beyond its capacity. Co-managed scales the Fusion-side coverage without requiring you to immediately hire additional headcount.
You want strategic IT guidance without losing internal IT ownership
The vCIO layer gives your leadership team a technology roadmap and compliance posture without displacing your internal IT manager from their leadership role.
Co-managed is NOT a fit if:
- You have no internal IT staff (fully managed is the right model)
- You have 10 or fewer users (too small for co-managed economics)
- You need Fusion to be your primary help desk contact (that is fully managed)
Frequently asked questions about co-managed IT
Pure managed IT without an internal team: managed IT services in Toronto, managed IT services in Vancouver, and managed IT services in Hamilton.
What is co-managed IT?
Co-managed IT is a service model where an external IT provider works alongside your internal IT team rather than replacing it. The co-managed IT provider fills the gaps that require 24/7 staffing, senior security expertise, and specialist depth — things a 1-to-5 person team cannot sustain alone.
How is co-managed IT different from fully managed IT?
The key difference is whether you have internal IT staff. Fusion fills the 24/7 NOC monitoring, security operations, Tier 3 escalation, and vCIO layers. Co-managed starts from $130 per user per month vs. $180 to $250 for fully managed, because your team absorbs the help desk.
What does a co-managed IT provider do?
A co-managed IT provider delivers the services your internal team cannot staff around the clock or at the specialist depth required. Fusion Computing delivers 24/7 NOC monitoring via NinjaOne RMM; CISSP-led security operations with Huntress EDR and SentinelOne XDR; Tier 3 escalation for complex infrastructure and security incidents; virtual CIO strategic advisory and quarterly business reviews; patch management backup.
How much does co-managed IT cost in Canada?
Co-managed IT in Canada starts from $130 per user per month for a scope that includes 24/7 NOC monitoring, CISSP-led security operations, Tier 3 escalation, vCIO quarterly reviews, and patch management backup. Fully managed IT runs $180 to $250 per user per month.
Who is co-managed IT for?
Co-managed IT services are for Canadian businesses that already have 1 to 5 internal IT staff serving 30 to 300 users. Co-managed is a strong fit for regulated industries (financial services, healthcare, legal, professional services) needing documented controls for OSFI, PHIPA, PIPEDA, or SOC 2.
Can co-managed IT work alongside our existing IT person?
Yes — working alongside your existing IT person is the entire point of co-managed IT. Fusion does not replace your IT manager’s decision authority or take over vendor relationships. Fusion adds the 24/7 monitoring, security operations, Tier 3 escalation, and vCIO advisory that your IT person cannot deliver alone.
What co-managed IT services does Fusion Computing offer?
Fusion Computing offers co-managed IT services from offices in Toronto, Hamilton, and Metro Vancouver, with remote coverage across Canada. Fusion is named to Canada’s 50 Best Managed IT Companies for 2024 and 2025. The service stack includes: 24/7 NOC monitoring via NinjaOne RMM; CISSP-led security operations with Huntress EDR, SentinelOne XDR.
How do we get started with co-managed IT?
The first step is a 20-minute assessment call with a Fusion senior consultant at no charge. We review your user count, internal team structure, current tooling, and the specific gaps you want to fill. From there we scope a co-managed engagement and provide a written proposal within five business days.
The Canadian co-managed cycle I plan around is the lone internal IT director who handles a Toronto Bay Street workload by day, a Hamilton manufacturer’s shop-floor outage at 6 a.m., and a Vancouver wealth-firm SOC 2 audit on the same calendar. They don’t need a replacement. They need a CISSP-led senior bench, an after-hours on-call rotation, and a written escalation matrix so the audit-evidence and the on-call sleep aren’t carried by one person.

How co-managed IT splits work between your team and ours
Co-managed IT services supplement your existing internal IT team with 24/7 NOC monitoring, advanced cybersecurity tooling, specialist skills (cloud, security, compliance), and surge capacity, without replacing in-house staff. Fusion Computing provides co-managed IT for Canadian SMBs with internal IT leads, typically from $130/user/month depending on scope.
According to Statistics Canada’s 2025 Canadian Survey of Cyber Security and Cybercrime, 43% of Canadian organizations were targeted by a cyber attack in the last 12 months. Most internal IT teams lack the 24/7 coverage required to respond in time.
According to the Canadian Centre for Cyber Security, ransomware attacks now typically move from initial access to impact in under 24 hours, faster than most internal IT teams can detect without supplemental MDR.
“Co-managed IT is where most Canadian SMBs should sit: retain the internal IT lead who knows the business, layer on the CISSP-led security controls, 24/7 monitoring, and specialist skills you cannot justify hiring for. Two teams, one accountability chain, and the internal lead stays senior.” – Mike Pearlstein, CISSP, CEO, Fusion Computing
