As three of Canada's largest cities grapple with civic elections, one issue defines and divides voters: how to handle traffic congestion in a way that is affordable, and politically palatable.

Reg Sherren in Winnipeg highlights the battle over bike lanes as the city tries to increase two-wheel traffic.
