“I got the call no business owner wants. Our systems were locked and there was a ransom demand on every screen. I called Fusion in a panic at 9pm on a Friday. They had someone working on it within the hour. By Monday morning our team walked in, sat down, and got back to work. Every in-scope file recovered. No ransom paid.”

What Happens After You Contact Fusion

A senior member of our Canadian team aims to review your enquiry and reply within one business day. Include the business problem or goal, approximate team size, current setup and timing if you know them. A support-provider change, Microsoft 365 project and AI workflow each need a different starting conversation.

The free 30-minute discovery conversation helps establish what your business needs and whether Fusion Computing can help. A paid assessment, implementation project or ongoing service follows a separate scope and proposal where appropriate. Sending the form requests a reply; the calendar link beside it lets you choose an appointment.

If you want to understand how Fusion works before reaching out, you can review the About page, explore the Case Studies page, or compare service paths through managed IT support and cybersecurity services. That context makes it easier to use the contact form well and gives the team a faster starting point when you do reach out.

Questions People Usually Ask Before Reaching Out

Who reviews the form submissions?
A senior member of our Canadian team aims to review your enquiry and reply within one business day. Share the business need and timing so we can discuss the right scope for managed IT, co-managed IT, cybersecurity or AI work.
Can I contact Fusion if I’m not ready to switch providers yet?
Yes. Plenty of businesses reach out while they’re still evaluating options. The point of the first conversation is to understand what isn’t working, what the immediate risks are, and whether a change actually makes sense now.
What if we have an urgent outage or security problem?
Existing clients should call 1-888-541-1611 or use the support portal. For a new-business enquiry about an urgent need, call (416) 566-2845 to discuss availability and scope.
What kinds of businesses are the best fit?
Managed services usually fit businesses with 10 to 150 employees across Toronto, Hamilton and Metro Vancouver. Smaller organizations can still ask about a scoped Microsoft 365, cybersecurity or AI project. Tell us what you need to achieve so we can discuss scope, cost and fit.
Are you the same company as Fusion Cyber Group?
No, we are separate businesses with similar names. Fusion Computing Limited is a Canadian-owned managed IT, cybersecurity, and AI consulting firm headquartered in Toronto, founded in 2012, and led by CEO Mike Pearlstein (CISSP). Fusion Cyber Group (fusioncyber.ca) is a different company. If you’re looking for Canadian-owned managed IT and cybersecurity for businesses with 10 to 150 employees, you’re in the right place.
Does Fusion Computing offer a free IT consultation?
Yes. The free 30-minute discovery conversation establishes your business need and whether Fusion Computing can help. Use the form to request a reply, or choose an appointment through the calendar link beside it. A paid assessment or implementation is scoped separately; the free call does not include an assessment report.
What does managed IT support cost?
Published starting prices are CAD per user per month: fully managed IT from $180, co-managed IT from $160, and CIS-Aligned MSSP about $230. Managed cybersecurity is $180 to $250+, depending on scope and requirements. Your written proposal confirms the services, inclusions and price.
