IT services and support in London, Ontario

An IT company that's actually in London

Plenty of IT providers will put London, Ontario on a service-area list. Keystone Technologies works here. Our office is at 300 Wellington Street, Suite 200, in the core of downtown London, and the technicians who answer your call are the same people who show up at your door.

That matters more than it sounds. When a server dies or a network goes down, a national helpdesk can only tell you a ticket has been created. A local team can have someone on-site the same day, often within hours. And because we support businesses across the city, from professional offices on Dundas to manufacturers in the industrial parks, we already know the buildings, the ISPs and the quirks of doing business here.

We support organizations of 10 to 200 users across London and the surrounding region, including Sarnia, Woodstock, St. Thomas and Strathroy. Day-to-day help is remote-first for speed; hands-on work happens at your site.

Do you provide on-site IT support in London?

Yes. Our team is based at 300 Wellington Street in downtown London, so a technician can be at most London businesses the same day, often within hours for urgent issues. Day-to-day support is handled remotely for speed, with on-site visits whenever hands-on work is needed.

How fast do you respond to IT problems?

Most critical issues are responded to within 15 minutes during business hours, with active resolution starting immediately. Non-critical tickets are typically resolved within 4 hours.

Do you only work with businesses in London?

London is home base, but we support businesses across Southwestern Ontario, including Sarnia, Woodstock, St. Thomas and Strathroy. Remote-first support means distance rarely matters, and we schedule regular on-site coverage across the region.

What does IT support cost in London, Ontario?

Our managed IT plans are flat-rate and priced per user, so costs stay predictable as you grow. Most small businesses find a managed plan costs significantly less than one in-house IT hire, while covering the full stack. A free consultation gets you a written quote with no obligation.
