Top Tech Startups in Ontario, Canada in 2027

Primate Labs Inc. develops Geekbench, the industry-standard benchmark for desktop systems and mobile devices.

Thor’s Hall is building a performance-based network for creators, publishers, marketers and online communities. We help partners monetize their audiences without having to build the technical infrastructure themselves. Thor’s Hall handles dedicated landing pages, campaign tracking, reporting and partner management while our partners focus on bringing quality traffic through the channels they already understand. Our model is simple: if a partnership generates revenue, everyone involved shares in the results. We currently focus on online gaming and iGaming, with the goal of building a wider network of creators, publishers and growth partners across multiple markets. We are still early, which means the people joining now have the opportunity to help shape how Thor’s Hall grows, test new acquisition strategies and potentially develop long-term partnerships as the network expands.

TECHNOLOGIES DEVELOPMENT COMPANY

Taskclan is a Canadian AI company building an integrated ecosystem across six connected pillars. Taskclan Intelligence develops our T1 model family: T1 Core, T1 Flow and T1 Max. Taskclan Cloud delivers AI infrastructure through Cloud Console and Cloud CLI. Taskclan Studio houses T1 Studio, where people and teams can build with our intelligence. Taskclan Engine transforms these shared capabilities into products, including GameNova, Nani, Forge3D and Spaces, TalentKit, ProposalAI and Ostrae. Taskclan Enterprise provides the governance organizations need through policy and residency controls, audit logs, SAML and SSO, and licensing. Taskclan Lab explores new technologies, experiments and future products. Each pillar strengthens the others: Intelligence creates the capabilities, Cloud delivers them, Studio makes them accessible, Engine proves them through products, Enterprise brings them to organizations, and Lab explores what comes next. We are a Toronto-based, remote-first team bringing together ambitious builders who want meaningful ownership and a direct role in building the next generation of Canadian AI.
