Fusion Computing is a Canadian-owned managed IT and cybersecurity firm serving businesses across Toronto, Hamilton, the GTA, and Metro Vancouver since 2012. We operate as a true IT department for our clients. Not a helpdesk you call when something breaks. We provide 24/7 coverage, resolve 93% of issues on first contact, and hold a 1-hour critical response target. CISSP-led security leadership on every engagement. No offshore helpdesks. No junior technicians on escalations. We specialize in Microsoft-first environments built to real security frameworks: CCCS Baseline Controls, CIS Controls v8.1, PHIPA, and PIPEDA. We serve businesses with 10 to 150 employees: manufacturing, healthcare, professional services, legal, financial services, and trades. We run four service lines: fully managed IT, co-managed IT, managed cybersecurity, and AI enablement and automation, with virtual CIO advisory across all of them. Named to Canada's 50 Best Managed IT Companies two consecutive years. Canadian-owned and Canadian-operated.
