Training at CZBB might not be the smartest thing to do. It's much more expensive compared to the other airports nearby. Most of the airwork is done farther from the airport so there's about a 10-15 min flight to get there, and then theres always a line to take off. So your bill comes to about $20-30 more each flight (though you need those hours anyways, many people would rather really fly those hours than go straight for 15 minutes, find out the training area is full with 5-10 aircraft, fly another 10 min and then start training.
Personally I would suggest training at Pitt Meadows airport (CYPK). It's only a few miles from Boundary Bay (CZBB). It's much closer to the training areas, it's a lot less busy. Occasionally you'll find 5 people in the circuit due to newbies from Boundary Bay and Langley coming in (Langley has a very short runway and obstacle clearance for both t/o and ldg). Also, you'll never get lost at CYPK. You can fly to almost any airport nearby by following a river. If you get lost at Boundary Bay and you stray into US territory, be afraid. =P I'm serious though.
