Now I wouldn't let my dislike for shore dives prompt me to bring this up, but...
Our dive store uses Sea Dragon Charters out of Horseshoe Bay and I believe they do two dives air included for $99. They know all the good sites and it's way easier to access them by boat because of the steep terrain in West Van and the Sea to Sky corridor.

Just a option to keep in mind.
