In Montréal, what started as an emergency pandemic response has evolved into the continent’s most ambitious car-free scheme.

Vision Zero answers “Where are the greatest number of injuries within our jurisdiction” But shouldn’t we also ask “Which communities have the greatest fatality rate for each resident walking or biking, and especially walking to and from bus stops.”
