Another option is Focal Point, up on W. 10th Avenue near UBC. They have been in the darkroom and studio rental business in Vancouver since the mid(ish) '70s. (I took my first class there in 1976 as a break from studies at UBC)

There are currently 6 individual darkrooms (tray processing for prints or film processing) available. Four with Beseler 23Cs (up to 6x9 cm) and a couple with Omega D5s (up to 4x5 inches).

As they also run classes you need to check with them regarding rental availability (604-224-3636)

(disclaimer, I've been both a student and an employee of Focal Point)
