Markham hosts first IndyCar race amid Canada's great circuit history

Markham is an unknown quantity until the cars actually run, so the more useful frame here is what Canadian circuits have had to offer historically — and that bar is genuinely high. Canada has produced tracks that demanded real commitment from drivers and delivered memorable racing, which is the standard any new venue is measured against. Whether Markham earns a place in that company depends entirely on what happens on track, not on ambition or infrastructure. The historical context makes this weekend feel like more than a debut; it's an audition against a serious legacy.
