As a newly-minted Canadian I've noticed that as well. I moved to Toronto from Istanbul five years ago and while I was away, Istanbul added 75 kilometers to its metro. That's longer than the entire Toronto Subway.
All this talk about being a world-class city, while nobody knows when Eglinton Crosstown, a "subway" line using streetcar ("LRT") tech that's been "in progress" since 2011, will open. Don't even get me started on SmartTrack :)
