I watched
Koop's video and was reminded of how well we can see the location of subway stations along Toronto's Yonge Line just by looking at the tower clusters. That's something that is very noticeable in some pictures and when flying in and out of TO, though it seems limited to Yonge and a handful of stations down University.

Vancouver has this too along many parts of Expo and Millenium. Not as much along Canada thus far, with a few exceptions
Montreal has virtually none of this, but the entire city was built with impressive low and mid-rise density from the very start, so TOD wasn't necessary.
Edmonton has just about no TOD along the lines at this point in time, while Calgary seems to have a small handful.
Ottawa's Transitway had mixed results. A few stations in the east-end had developed TOD early on (from the rental tower cluster at Lees, heavily occupied by post-secondary students, condo towers at Hurdman, and a few mid-rise office buildings at Blair, though plenty of parking). Most towers along the Transitway already existed. In the west end, I can think of only one significant project at Westboro (Metropole, built in the early 2000s, the tallest residential up until recently). The original O-Train too (Trillium) had poor results, with two towers built along an infill station that ended up being canceled. When the Confederation Line concept was officially launched, that's when we witnessed some true TOD. Trillium's Carling has seen at least six new towers, with about a dozen more proposed. Several towers have been built and countless more proposed in the urban west-end (Bayview to Lincoln Fields (Confed) and Bayview to Carling (Trillium)). Blair has one completed tower, one u/c and a few more proposed. A new tower is proposed at Bayshore, with a direct link to the station. In 10 years, we might see a low-scale versions of the Yonge Line.
