Cross Country Checkup is celebrating Canada Day weekend with two topics. First, in this post-Stanley Cup, pre-Olympic moment, we were thinking about the role sports plays in our national culture. Those events that bring us and bind us together, that don't just entertain... but inspire. Join Ian Hanomansing and long-time CBC Sports host Scott Russell as they hear your favourite Canadian sports moments. And some former Liberal politicians are calling on Justin Trudeau to step down as party leader. Do you think he should?
