I don't think we have any TOD in a strict sense, but plenty of "transit adjacent development". The difference is that we still always prioritize vehicles instead of transit in all our stations so we don't achieve most of the goals of good TODs, despite development.
Stations with TODs close by:
Dalhousie - Groves of Varsity (complete), The Dells (under construction)
Brentwood - University City (complete), Brio (complete), Brentwood Commons (proposed)
Heritage - London 1 & 2 (complete), London 3 & 4 (on-hold)
Westbrook - Westgate Park (complete), Calgary Public Library (complete), Corus Centre (complete), Uptown @ Westbrook (on hold)
Fish Creek - Manor at Fish Creek (complete), Highbury Tower (complete)
Dalhousie - freeway median station, parking and bus loops are far more prominent than any development nearby on both sides of the station despite recent development.
Brentwood - freeway median station plus suburban shopping mall and access roads on both sides. Parking more prevalent than anything, despite recent development.
Heritage - heavy rail, abandoned lots and free-flow traffic between development and station. A circuitous pedestrian bridge added that only improves the access to the LRT marginally from a terrible starting condition.
Westbrook - actual TOD, library physically built in station. No development yet but a rare example of where you could imagine true orientation to transit (minus Bow Trail semi-freeway).
Fish Creek - parking, freeways and heavy rail prioritized over development.
If we aren't able to remove the conditions that prevent good TOD (i.e. remove the complete vehicle hegemony in a station area) we can only look to the ones where vehicles haven't complete dominated. Banff Trail, Lions Park, 45 Street SW and the city centre are easily the best candidates. Sunnyside is probably the winner in true transit-orientation of development and actually following through on it for any station beyond 7th Avenue. Most stations, due to our decisions decades ago to run our LRT system in medians and along heavy rail lines, will never be good TOD candidates.
There may be a few more TOD candidates if you could condense bus loops and remove acres of park-and-ride in favour of development but most are lost causes without massive (and probably controversial) interventions. Perhaps 39 Avenue S or Chinook one-day. A few of the Greenline stations (but not many) have a chance too. Some along 36 Street NE might be a bit easier on account of it being just a terrible, vehicle-oriented road and not an actual freeway.
