I've spent over ten years in the Lower Mainland of BC and my experience is only limited to the Vancouver area but I've heard rave reviews from serious BC divers about Port Alberni.
It's a bit of a distance but it would make a pleasant trip on land as well (the western side of Vancouver Island is very scenic and relatively unspoilt).
