What Clients Say About Working With Fusion

I got the call no business owner wants. Our systems were locked and there was a ransom demand on every screen. Fusion had someone working on it within the hour, and by Monday we were operating normally again with no ransom paid.

Sandra M. , CEO, Industrial Supply Company

Fusion mapped AI opportunities to our actual day-to-day workflows, deployed Copilot for leadership, and built automation that cut month-end reporting from two days to four hours.

Rachel D. , Managing Partner, Financial Planning Firm, Toronto

It’s refreshing to work with a technology vendor that’s reactive in an expedient manner to our needs as a business. Fusion takes the time to learn what your current and future goals are, offers options to help you achieve them, and make you feel like your business is valued.

Frequently Asked Questions About Fusion

What does Fusion Computing do?

Fusion Computing provides managed IT services, cybersecurity services, strategic IT leadership, and AI consulting for Canadian businesses. We help clients with day-to-day support, security improvement, planning, vendor management, and modernization initiatives through one accountable partner.

What size businesses does Fusion work with?

Fusion is best suited to small and mid-sized businesses that need dependable IT support, stronger security, and clearer technology planning. Many clients are large enough to need structure and responsiveness, but not large enough to justify building every specialty in-house.

Does Fusion offer fully managed and co-managed IT?

Yes. Fusion can operate as your full outsourced IT partner or work alongside your internal IT staff in a co-managed model. The right fit depends on your team structure, internal capacity, and the level of strategic or technical depth you need.

How quickly does Fusion respond to IT issues?

Fusion targets a 1-hour response time for critical issues and focuses on resolving problems quickly through experienced support, not unnecessary escalation. For many clients, the biggest difference is that issues move forward faster because the team already understands the environment.

How do I get started with Fusion?

Start with a conversation about your current environment, business priorities, and the gaps you want to solve. If there is a fit, Fusion can scope the next step, whether that is an IT assessment, a support transition, a security review, or a planning engagement.

Where does Fusion work?

Fusion is headquartered in Toronto, with additional presence in Hamilton and Vancouver, and supports businesses across Canada. When hands-on work is required, Fusion provides on-site coverage in its core service regions and remote support more broadly.

From 35 to 205 users in under 4 years

A Toronto design studio partnered with Fusion to rebuild their IT environment from the ground up. Today, the co-managed engagement has been running for 5+ years.
