Canadian-owned MSP · Since 2012
About Fusion Computing
Still led by the same CISSP-certified engineer with an MSc in Computer Science from the University of Guelph who started it.
Mike Pearlstein built Fusion Computing as a focused managed IT and security practice for Canadian SMBs. What started as a one-person operation has grown into a regional IT partner serving businesses across Toronto, Hamilton, and Metro Vancouver, but the approach hasn’t changed: senior people, direct accountability, and no hand-offs to junior techs when it matters.
Business IT only. Best fit for organizations with 10–150 users.

How Fusion started
- 2012Mike Pearlstein leaves a career in enterprise IT and starts Fusion solo, building the kind of MSP he’d want to hire.
- 2020Already built remote-first, Fusion grows through the pandemic and expands into Hamilton and Metro Vancouver.
- 2025Named to Canada’s 50 Best Managed IT Companies (2024 and 2025).
Mike started Fusion because most MSPs serving Canadian SMBs were either too small to handle real security work or too large to give clients direct access to senior people. Growth has stayed deliberate: every new client means owning the whole IT environment, not just the easy parts.
A structured security program built on the CIS Controls v8.1 framework. The same team that runs day-to-day support implements it, and it produces the audit-ready documentation insurers and auditors actually ask for, with no internal security build required.
The team has grown well beyond the founder, into a senior Canadian crew that owns the work day to day. Meet the full Fusion Computing team → or review the technology partners and certifications behind it.
Security leadership, not just security tools
Mike Pearlstein holds the CISSP from ISC2 and an MSc in Computer Science from the University of Guelph (2011), where his research focused on artificial intelligence. Fewer than 1% of Canadian MSP leaders hold the CISSP.
“I earned the CISSP so that when a client faces a real security decision, it’s made by someone accountable for the answer, not handed off to a vendor’s sales deck.”

What CISSP-level leadership means in practice:
- Insurance questionnaires: clients get answers, not a blank template to fill out themselves.
- Tool decisions: someone in the room can tell whether a new EDR closes a real gap or just adds another dashboard.
- A live breach (one client came to Fusion mid-incident): the response runs under someone with the training and judgment to manage it.
A 45-employee industrial supply company in Mississauga was hit by ransomware on a Friday evening.
Fusion restored operations from verified air-gapped backups and had staff working by Monday morning, with zero data loss and no ransom paid (62 hours, detection to production).

Frequently asked questions
Fusion Computing is a Canadian-owned MSP delivering managed IT services, managed cybersecurity, and AI and Microsoft Copilot deployments to small and mid-size businesses across Ontario and British Columbia.

Why this matters for Canadian SMBs: Canada has roughly 1.2 million small and mid-size businesses according to ISED, and Statistics Canada reports that more than 70% of Canadian firms experienced a cybersecurity incident in recent reporting cycles. The Canadian Centre for Cyber Security flags ransomware as the top threat to Canadian SMBs, while the IPC of Ontario and OIPC of BC enforce breach-notification timelines under PHIPA and BC PIPA. A CISSP-led, Canadian-owned MSP with offices in Toronto, Hamilton, and Vancouver shortens the path between incident detection, regulator notification, and cyber-insurance evidence.
