I moved to Ottawa from Winnipeg (quite) a few years ago...
Winnipeg is slightly smaller than Ottawa, but doesn't have a single freeway. Only highway (and it's not even controlled access) is the Perimeter Highway, which basically a ring road well outside the city proper...
It takes for-freakin ever to get from one side of Winnipeg to another, traversing probably 40+ traffic lights on the way.
First thing I noticed when I moved to Ottawa was:
a) This awesome highway where one could zip from one side of the city to another in 20 minutes
b) a) was even better because 100 km/h really means 120 km/h
c) These awesome parkways (QE Drive, SJAM) where one could zip around the city without too many traffic lights and other distractions.
Demolishing the Queensway is such a silly topic I would suggest this thread be deleted... or at very least the OP move to Winnipeg for a couple of years and experience the alternative
