I'd go bigger; a comprehensive and cohesive transportation plan is necessary. I'm talking rail and air. Granted HSR is much more difficult to justify in the west but out east someone needs to standup and properly plan our transportation networks. And eventually, if we want to improve our living standard, HSR between bigger western cities is important (Winnipeg, Regina, Saskatoon, Calgary, Edmonton, Kelowna, Kamloops, and Vancouver). If we continue to concentrate our growth in so few cities, those tier 2 cities will begin to become unaffordable as well.
