Fusion Computing Limited

Fusion Computing Limited is a Canadian-owned managed IT services provider headquartered in Toronto, with presence in Hamilton and Metro Vancouver. Since 2012, we have delivered managed IT, cybersecurity, vCIO/vCISO and AI consulting services to businesses with 10 to 150 employees. Our security practice is led by a CISSP-certified CEO and aligned to the CIS Controls v8.1 framework. That means a structured, auditable approach to cybersecurity, not just tools and hope. We operate as an extension of your team, whether that is full managed IT or a co-managed model alongside your internal staff. Core services include managed IT support with first-contact resolution, cybersecurity services (endpoint protection, email security, vulnerability management, incident response), vCIO and vCISO strategic advisory, IT procurement, Microsoft 365 management and AI consulting including Microsoft 365 Copilot deployment. We serve industries including accounting, construction, design, manufacturing and non-profit organizations, with particular depth in regulated environments requiring privacy and compliance frameworks like PHIPA. We do not just keep the lights on. We align technology to business outcomes through structured IT business assessments, proactive security posture management and strategic roadmapping. Our clients stay because the relationship works. One design studio grew from 35 to 205 users over a 5+ year co-managed engagement with us.
