That's something I wish was do able in Ontario. Cars are downright hostile to cyclists here. One in 300 will actively try to "buzz" you or "roll coal" you in bike lanes or intersections. Even biking with my kids exclusively in protected lanes and using pedestrian crossings I've had more close calls than I can count. Some of these drivers (willingly or thorough sheer carelessness) go out of their way to endanger CHILDREN.

Driving on the road taking up a lane requires a lot of focus and attention to keep yourself safe from the significant minority of drivers who actively disdain you. And that's when you move to the side to let them illegally pass you at every opportunity. If you tried to take a full lane for any significant amount of time in Ontario you will 100% be hit on purpose. Maybe not every ride, but you wouldn't survive a summer of "using your legal right to a full lane".
