Overview

• Markham will host the event on Aug. 14–16, 2026 on streets bounded by Kennedy Road, Enterprise Boulevard, the Unionville GO tracks and Highway 407.
• The temporary circuit is planned as a 12-turn, 3.52‑kilometre (2.19‑mile) layout with a double‑sided pit lane designed by Tony Cotman of NZR Consulting.
• Green Savoree Racing Promotions and the city describe the agreement as multi‑year, with no official term disclosed despite some reports of a five‑year length.
• The move ends the race’s run at Toronto’s Exhibition Place dating back to 1986, following recent one‑year arrangements and anticipated 2026 FIFA World Cup conflicts.
• Officials project more than 140,000 attendees and tens of millions in economic impact, with early site work and coordination underway with Metrolinx and local partners.
