Business IT support for your Toronto team
Fusion Computing handles day-to-day help desk requests, Microsoft 365 issues, remote troubleshooting and on-site work across the GTA. Fully managed IT places the agreed environment with our team; co-managed IT adds capacity around your internal lead.
We have served Canadian businesses since 2012. Toronto support operates from 100 King Street West, Suite 5700, with a named account lead, documented systems and a CISSP-led security practice. Our published first-contact resolution figure is 93%.
Our usual managed-service fit is 10 to 150 employees. A smaller firm can ask about a scoped setup or migration project. For the full management scope, see Managed IT Services Toronto.
What Toronto Businesses Say
4.9/5 on Google Reviews, verified by clients across the GTA since 2012.
★★★★★“We’ve been with Fusion for three years. The response time is consistently under an hour for anything urgent. Our King Street office relies on them for everything from new-user setup to firewall changes, and they have never missed a deadline. The named account lead model is the best decision we made when choosing an IT provider.”
Toronto-based financial advisory firm, 28 users, King Street West
★★★★★“We switched to Fusion because our previous IT company took days to resolve basic issues. Now our staff calls Fusion directly and most problems are fixed within the hour. The compliance documentation they provided for our LSO practice review was thorough and saved us at least a week of internal preparation time.”
Toronto-based law firm, 35 users, Bay Street
★★★★★“Our clinic went through an IPC Ontario audit last year. Fusion had our PHIPA safeguard documentation, access logs, and backup verification records ready in 48 hours. The auditor had no questions about our IT controls. That outcome would not have been possible with our previous reactive provider.”

Compare IT support options before choosing a provider
Choose who should own the work before comparing monthly totals. Fusion Computing offers fully managed and co-managed IT; an internal team is a separate staffing choice.

| Decision | Fusion fully managed IT | Fusion co-managed IT | Internal IT team |

| Who owns the work | Fusion Computing runs the agreed support and management scope. | Your internal lead keeps ownership; Fusion Computing takes the agreed responsibilities. | Your business hires and manages the team and its outside specialists. |
| Published starting price | From $180 CAD per user/month. | From $160 CAD per user/month, plus your internal team. | Salary, benefits, tools and any outside coverage depend on your staffing plan. |
| Coverage and escalation | 24/7 capability; response objectives and on-site scope are written into the proposal. | Coverage, shared queues and escalation are agreed with your internal lead. | Coverage follows your staffing, rota and escalation arrangements. |
| Records and continuity | A named account lead, documented systems and tracked support requests. | Shared documentation and ticket visibility support your existing team. | Your team maintains documentation, ticket records and cover for absences. |
| What to compare in a proposal | Users, systems, licences, security scope, on-site work and projects. | The division of responsibility, overlap, handoffs and escalation. | The skills and cover you need to resource internally or purchase separately. |
For 25 users, the published starting rates illustrate $4,500 per month ($54,000 per year) for fully managed IT or $4,000 per month ($48,000 per year) for co-managed IT, before your internal team costs.

IT support pricing and fit in Toronto
Fusion Computing’s fully managed IT starts at $180 CAD per user per month. Co-managed IT starts at $160 CAD per user per month and is scoped around your internal team. Team size, locations, systems and required coverage shape the written proposal.
Our usual managed-service range is 10 to 150 employees. Smaller businesses can ask about a scoped setup or migration project, or ongoing support that fits their needs. Project work is scoped separately.
A free 30-minute discovery conversation establishes your needs and whether Fusion Computing can help. We aim to reply within one business day; a scoped assessment is a separate agreed engagement.

What’s Included in Fusion’s IT Support
The written proposal identifies the support functions, users, systems, licences and on-site work included in your Toronto engagement.
Help Desk Access
Your team reaches our help desk by phone, email, or chat, and a senior engineer responds directly. No phone tree, no tiered queue. A named engineer owns the ticket from open to close, so there is no handoff delay when you call back. Our 1-hour response objective for critical issues guides support coverage and escalation, which matters when a downed trading terminal or a locked-out compliance officer costs thousands per hour.
Remote Support
Hybrid work is the default for Toronto businesses now. Your Bay Street staff, your Yorkville account managers, and your work-from-home team all reach the same help desk and the same engineer pool, not separate tiers, and 93% of issues are resolved on first contact.
On-Site Dispatch
When remote is not enough, our Toronto field team dispatches from 100 King St W and reaches most GTA locations within 4 hours for priority issues. Hardware replacements, structured cabling, network troubleshooting, and workstation setups are handled by the same engineers who answered your remote ticket, not a subcontracted field tech. Outer 905 and Hamilton dispatch is available and priced on scope.
Device Management
We provision, patch, and manage laptops and desktops with remote monitoring and management. New hires get a hardened golden image, credential management, and MFA enrollment before day one; departing staff are offboarded within the same business day, with Entra ID disabled, Microsoft 365 licenses reclaimed, and endpoints wiped to NIST 800-88 standard. Conditional access under a unified Intune policy gates every corporate app to compliant devices across Windows, macOS, iOS, and Android.
Monitoring and Alerting
remote management agents watch every workstation and server for failing disks, patch gaps, and offline endpoints, and managed threat detection flags suspicious activity around the clock. Alerts route to the same Toronto help desk that answers your calls, so the engineer who sees the warning is the one who fixes it, often before you notice.

How Onboarding Works: 90 Days to Fully Covered
Most Toronto businesses that switch to Fusion are fully operational on our stack within two weeks. The full 90-day onboarding clears inherited IT debt before it becomes your emergency.
Days 1-14: Discovery and Baseline
We document your full environment: servers, workstations, SaaS stack, cloud tenants, and network topology. Remote management and monitoring go live and your named account lead meets every department head. We identify every inherited security gap before it becomes your problem.
Days 15-45: Remediation and Hardening
Patch cycles are standardized. Managed detection and endpoint protection deploy to every endpoint. Passwords move to credential management, MFA is enforced sitewide, and backup integrity is verified with a live restore test. Compliance gaps found in discovery get remediated and documented.
Days 46-90: Steady State and Review
Your team knows how to reach us and what to expect for every issue type. Monthly ticket-trend reports show resolution times. Before onboarding, an IT health check establishes what we are measuring against. At day 90, your account lead delivers a written technology baseline and a 12-month priority list, and the first on-site quarterly review is scheduled.
How to compare IT companies in Toronto
Compare each written proposal against the work your Toronto business needs. Check response objectives and on-site coverage, the users and systems included, licences and security responsibilities, and the process for handing over records when the agreement ends.
If you retain an internal IT lead, agree which team owns user requests, patching, onboarding and security escalations. Client references should help you assess work at firms with similar systems and requirements.
For a migration, audit or technology roadmap, see IT consulting services in Toronto. Our IT support versus managed IT guide explains the model distinction.
Why Toronto businesses need IT support with a security spine
- The National Cyber Threat Assessment 2025-2026 describes ransomware disrupting Canadian business operations, damaging data and exposing sensitive information. A Toronto support agreement should identify who handles access controls, backup recovery and incident response.
- The Cyber Centre’s Ransomware Threat Outlook 2025-2027 reports 336 early ransomware warnings to more than 300 Canadian organizations in fiscal 2024-2025, with economic savings of up to CAD $18 million. These are national figures.
- For CIRO-regulated investment dealers, CIRO’s 2026 Compliance Report addresses outsourcing risk and incident reporting under Rule 3703. Fusion Computing supplies agreed technical records; your firm’s compliance owner determines which obligations and evidence requirements apply.
Fusion Computing scopes security coverage, response responsibilities and reporting around your Toronto business, its systems and the work retained by your team. These responsibilities belong in the written proposal.
Compliance Coverage for Toronto Industries
Toronto’s regulated industries need IT support that speaks the compliance language of the sector. Here is what we cover and how it maps to your obligations.
OSFI E-21 and E-23
OSFI E-21 aligned security-controls documentation, remote management change-management logs, and incident-response runbooks formatted for OSFI board reporting. For E-23 clients we document IT controls around model infrastructure and separation of duties between production and test.
PHIPA and IPC Ontario
For Discovery District clinics and allied-health practices: PHI-isolated network VLANs, encrypted backups with daily verification, audit-ready access logs across Accuro EMR, OSCAR, and TELUS PS Suite, and a 14-point PHIPA safeguard checklist delivered to your Privacy Officer on day one.
SOC 2 Type II
King East and Discovery District SaaS scale-ups face SOC 2 evidence requests before contracts close. We supply the infrastructure-side evidence: endpoint-management records, MFA enforcement reports, backup verification, and change logs mapped to the Trust Services Criteria.
PIPEDA and Law 25
Every Toronto business handling personal information answers to PIPEDA, and firms with Quebec customers also carry Law 25 obligations. We maintain the technical safeguards both expect: access controls, encrypted storage, breach detection with notification-ready logging, and data-residency mapping for cloud workloads.
Industries We Support in Toronto
Business IT support built around the compliance, workflow, and risk realities of five Toronto verticals we know deeply, each profile drawn from live client engagements.
Accounting and bookkeeping firms
After-hours patch windows scheduled around CPA Canada busy season so no firm files late because of a Windows update. We support CaseWare, QuickBooks, Xero, Sage 50, TaxCycle, and Microsoft 365 with scoped 7-year CRA retention, and we pre-configure and test the CRA MyBA conditional-access policy before T1 season. One Toronto firm cut 4.5 hours of weekly partner time after we moved roaming profiles to OneDrive Known Folder Move and standardized an MFA baseline.
Law firms and legal practices
Privilege-first design: matter-based access in Clio or PCLaw, legal-hold compliant retention in Microsoft 365, encrypted client portals, and managed threat detection plus endpoint protection on every endpoint. We deliver LSO-formatted documentation that satisfies the Law Society’s MFA, encryption, and incident-response requirements, with a 1-hour critical response objective and CISSP escalation that keeps trial-ready laptops and iManage drives unblocked on court days. Rolling out Copilot next? Our guide to integrating Microsoft 365 Copilot with NetDocuments and iManage covers the DMS side.
Healthcare clinics and medical practices
PHI-isolated network VLANs, encrypted off-site backups verified weekly with a documented restore test, and audit-ready access logs across Accuro EMR, OSCAR, and TELUS PS Suite, with the 14-point PHIPA safeguard checklist handed to your Privacy Officer on day one. A multi-site Ontario primary-care group cut after-hours on-call pages by 61% after we rebuilt their clinical-versus-guest Wi-Fi separation and locked down kiosks to CIS Benchmark Level 2.
Professional services and consultancies
A standardized remote management-administered endpoint image, Microsoft 365 with conditional access, and a Teams Phone deployment that works from home, office, and client site without a handoff glitch. One Toronto consulting firm cut onboarding from 3 days to 4 hours with our golden-image deployment plus credential management SSO.
For strategy-level engagements, IT consulting in Toronto runs through our virtual CIO practice, and businesses outside the GTA can lean on our national IT support for small business coverage.
Field services, skilled trades, and finance
For field teams: ruggedized endpoints, ServiceTitan, Jobber, Housecall Pro, and Dynamics Field Service integrations, plus Starlink or LTE failover. A Toronto HVAC contractor reclaimed 90 minutes per tech per day after we replaced an aging MDM with Intune and job-site Wi-Fi profiles. For Bay Street wealth managers, CIRO dealer members, and fund administrators, we run IT support with compliance evidence (access reviews, MFA enforcement, incident documentation) produced as routine output an OSC or CIRO review can read.

“Fusion picked up where our last MSP stalled out. They walked our managing partner through what the cyber insurer actually needed, rebuilt our MFA stack in 14 days, and gave us evidence packs we could send straight to our LSO reviewer. Response times dropped from hours to minutes.”
IT Support Toronto: Frequently Asked Questions
How quickly does Fusion respond to IT support requests in Toronto?
For critical issues, our response objective is 1 hour. For Bay Street and Discovery District clients with intraday compliance obligations, the 1-hour response objective is designed to meet the tolerance expectations of a regulated Toronto business environment.
What is the difference between IT support and managed IT services?
IT support is responsive day-to-day coverage: your team contacts us when something breaks or someone needs help, and a senior engineer works to resolve the ticket against the agreed service level objectives across help desk, remote support, and on-site dispatch. If you want a full technology partner involved in annual planning and capital budget, see Managed IT Services Toronto.
Do you offer on-site IT support in Toronto?
Yes. On-site dispatch to Bay Street, King Street West, Adelaide Street East, the Distillery District, Liberty Village, Yorkville, and the Discovery District is typically sub-30 minutes on foot for PATH-connected offices. For the broader 416 and GTA inner ring, we target a 4-hour on-site response for priority issues.
Can you support our team after hours and on weekends?
Absolutely. Our help desk is staffed 24/7, 365 days per year, so critical issues do not wait until Monday. managed detection and response also monitors endpoints continuously and can isolate a compromised machine autonomously before the on-call engineer is even paged.
What tools does Fusion use for IT support and security in Toronto?
Fusion Computing provides support ticket tracking, secure remote assistance, endpoint monitoring and patching, managed detection and response, credential management and technical documentation. Microsoft 365, Entra ID and Intune support are scoped to your environment. Your proposal identifies the capabilities and licences included.
How much does IT support cost in Toronto?
Fusion Computing’s fully managed IT starts at $180 CAD per user per month; co-managed coverage starts at $160 CAD per user per month. Users, locations, systems and support responsibilities affect the quote. Your written proposal specifies coverage, included licences, on-site work and any separately priced services.
Does Fusion only support businesses in downtown Toronto?
No. Our 4-hour on-site response objective covers the entire 416 and GTA inner ring, including North York, Scarborough, Etobicoke, the Mississauga inner ring, Brampton, Markham, Vaughan, and the Yonge corridor north to Richmond Hill. Remote support serves clients across Ontario and Canada with the same 1-hour critical response objective regardless of location. For the full national overview, see our IT support hub .
How should we shortlist IT companies in Toronto?
Compare five things in writing: the response objectives and coverage, whether security (MDR, identity protection, incident response) is included in the base plan, real on-site coverage, published per-user pricing, and client outcomes from your industry. Fusion publishes $180+ CAD per user/month, with scope confirmed in writing, targets a 1-hour response for critical issues, and runs CISSP-led security oversight from King Street West.
Is Fusion Computing an IT support company or an IT consulting firm?
Both, under one roof. This page covers ongoing IT support: help desk, on-site dispatch, patching, and 24/7 security monitoring under a monthly per-user plan. For project-based work such as cloud migrations, IT audits, or a technology roadmap, Fusion’s IT consulting services in Toronto handles scoped engagements with defined deliverables and timelines.
