Built In’s “largest tech companies in Canada” article is best read as a directory of technology and technology-related employers with Canadian operations—not as a verified ranking by revenue, workforce, valuation, or market share. It includes both Canadian organizations and multinationals, with profiles spanning infrastructure, financial technology, healthcare, gaming, and more.
What “largest” means in this list
Built In updated its editorial overview on Aug. 26, 2026. The accessible article does not explain how it determines “largest,” provide comparable size figures, or establish that profile order reflects company size. Treat it as a selection of notable employers with Canadian offices or teams, not a ranked market study. Built In’s article is the place to check for its current presentation and roster.
Its profiles also do not make every company Canadian-founded or Canadian-headquartered. Canadian presence can mean an office, employees, or hiring activity; the location examples include Toronto, Montreal, Vancouver, Burnaby, and Calgary. Those details can change, so confirm the relevant company’s current careers or location information before relying on a specific opening or office.
Companies and sectors represented
The roster crosses several kinds of technology work. These examples describe what the companies do; they are not size tiers or ranking positions.
#1 Best Overall
| Sector or work | Examples in the Built In profiles |
|---|---|
| Semiconductors, AI, and connectivity | Arm; Ericsson |
| Financial software, investment research, payments, and money transfers | Broadridge; Morningstar; Airwallex; Mastercard; Remitly; TD Bank |
| Cybersecurity and digital operations | Zscaler; PagerDuty |
| Healthcare, biotechnology, and pharmaceutical services | Novo Nordisk; Cencora; ZS |
| Gaming, lottery, and digital assets | Scientific Games; Coinbase |
| Business, workplace, and consumer-facing technology | Applied Systems; AdCellerant; H&R Block; 360Learning; Capco; Amadeus; Luxury Presence; Magna International |
| Staffing | Aerotek |
This spread matters for job seekers: a “tech company” here may build core infrastructure, sell software to enterprises, provide technology-enabled financial services, or use technology in a broader business. The list is useful for discovery across those categories, but it does not assess workplace quality or establish which employer is best to work for.
How to use the list if you are job hunting
- Start with the type of work. Narrow the roster to sectors and products that match your experience or interests—for example, cloud security, payments, travel systems, or automotive technology.
- Check the specific Canadian presence. Look at the employer’s current careers pages for location, team, and role details. A profile mentioning Canada does not guarantee an office or vacancy in a particular city today.
- Evaluate the role, not the list order. Compare responsibilities, required skills, location expectations, and employment terms in the live posting. Built In does not provide a common employer-rating or job-quality measure for these profiles.
One notable figure—and its limits
Built In attributes $120 billion in annual lottery sales processed to Scientific Games. The article does not state a year for that figure, and it should be understood as a company figure reported by Built In, not as an independently audited measure or a basis for comparing the listed companies’ size.
