With the dust settled after a thrilling weekend of action at Canadian Tire Motorsport Park (CTMP), the IMSA WeatherTech SportsCar Championship has officially entered its high-stakes final stretch.

The margin for error has evaporated. For the high-flying prototypes of GTP and LMP2, only three rounds remain to crown a champion. Meanwhile, the production-based warriors in GTD Pro and GTD have four rounds left, including their highly anticipated standalone GT weekend at Virginia International Raceway (VIR) next month.

Here is how the championship tables stack up across all four classes as we head toward the season’s dramatic conclusion.

GTP: Cadillac and Aitken Control the Crown

The premier hybrid class is turning into a heavyweight duel between GM’s factory effort and the global powerhouse of Porsche. Thanks to a relentlessly fast campaign, Jack Aitken holds a commanding lead in the driver's championship, keeping Cadillac comfortably ahead in the manufacturer race.
