The “no more roads” policy and the analysis that you didn't do.... That's why you're here.
Again, I'm going to state this: In Toronto, it takes 29 minutes to drive 10 kilometres. It's the third-slowest in the world in terms of traffic patterns. In Vancouver, it's 23 minutes to drive 10 kilometres. In Winnipeg, it's 19 minutes. In Montreal....
I have a whole list of cities around the country, big and small. All of the them have one thing in common: traffic congestion. We need roads. Those are just for folks who live in the cities. I suspect that you know that you can't use a bike lane in most rural ridings. You certainly can't walk to work or walk to drive your kids to hockey.
What do you mean when you say, “the network is perfectly adequate to respond to the needs we have”? It's blatantly untrue. This is not even an analysis; it's just facts.
