IMSA heads to the Great White North this weekend for Round 6 of the WeatherTech SportsCar Championship, the Chevrolet Grand Prix.

Canadian Tire Motorsport Park will host 34 cars in four classes on the 3.957km course for the 160-minute minute Sprint race.

The circuit, east of Toronto, has hosted an IMSA since 1999.

The event is the third of seven sprint races on the IMSA schedule.

IMSA announced earlier this week that Balance of Performance (BoP) changes would take place in the GTP and GTD classes.

The Acura ARX-06, the BMW M Hybrid, and the Cadillac V-Series. R will receive weight reductions of 7kg while the Porsche 963 receives a 6kg reduction.

Acura and BMW will receive a three MJ energy reduction, while the Cadillac and Porsche will receive a two MJ reduction.

Five makes in the GTD class will see BoP increases in horsepower and fuel capacity.

The power-related changes are expected to be an increase between 6-8hp (4.5-6kW) and will benefit the Acura NSX GT3 Evo22, the McLaren 720S GT3 Evo, the Mercedes-AMG GT3, the Porsche 911 GT3, and the Corvette C8.R.

The Porsche received the biggest adjustment, while the Corvette received the smallest increase in power.

Additionally, fuel capacity increased by up to two litres in the GTD cars receiving the horsepower increase.

The #3 Porsche Penske 963 of Matthieu Jaminet and Nick Tandy are in third place in the GTP class after their victory was taken away at Watkins Glen, which saw the# 25 BMW M Team RLL BMW M Hybrid V8 declared the winner.

The Porsche duo trail the #31 Cadillac of Pipo Derani and Alexander Sims by 75 points and the #25 BMW of Connor De Phillippi and Nick Yelloly by 11 points.

The #74 Riley Sport Ligier of Felipe Fraga and Gar Robinson holds a commanding 124-point lead in the LMP 3 class.
