Given the hot tempers, dramatic finishes and contentious rulings IndyCar has already delivered this season, there's at least one thing drivers can agree on: Don't expect the drama to cool down up north in Toronto.

Sebastien Bourdais predicted there could be plenty of wrecks in the race Sunday.

Bourdais was referring to IndyCar's decision to reinstate its push-to-pass feature, providing drivers an additional boost of horsepower to assist in making passes. That extra speed will be available to everyone navigating the twisting, narrow, slick, 11-turn, 1.75-mile street course with a reputation of getting both the best and worst out of drivers.

And the bumping's already begun — in practice, no less — on Friday when Simon Pagenaud accused series points leader Will Power of blocking him in practice.
