It's a huge country so it's difficult to generalize, but in Vancouver/Victoria we're constrained by the ocean and the mountains, and by farmland. There's a strong but slowly diminishing opposition to medium-/high-density housing because neighborhoods of detached single family homes have defined the character of these cities for decades. It's been years since I lived near Toronto but the city is ringed in on all sides by the lake and what's called the Green Belt, which is a protected swathe of farmland and nature preserves. Toronto's doing a better job than Vancouver in terms of managing the density and growth, but every city has problems growing and we Canadians lack the culture of collectivism that makes Tokyo work.
