Episode 3x12: They Also Serve
Screencaps

Diving pool 788 Jervis St [49.287213,-123.127302]

They used to have a pool at this location but it was renovated and turned into a fitness centre and conference rooms.

Also, if I remember correctly, I think Steve Geaghan told us that the diving board was added for the episode - the pool was deep enough for one, it just didn't have one.

Street alley between Robson & Alberni [49.287676,-123.128487]

This alley is across the street from the apartment complex where the pool was.

Dam near cabin Seymour Falls Dam [49.371411,-122.948596]

This is a small runoff pond at the end of Mt Seymour Rd, on the other side of the Mystery Peak Express ski lift and up the hill from MacLeod's cabin.

Just down the road from Episode 1x07.
