Not stormy water (even with quite a few dives under my belt, I avoid diving in storms). And for Ontario 15C is downright warm. We dove near Wiarton weekend before last, water was 49F (10C) at 60 feet.alias420:GroundHog sounds like you are saying that I should go and do my open water in 15C Stormy Water at 60ft? I think that would be far more dangerous then doing my open water in a pond.
While I agree somewhat with your analogy, doing your OW dives in conditions more similar to where you'll be diving, while being supervised by an instructor makes more sense to me. It'd be great if you did your OW dives at Gullivers or similar, followed by supervised dives in colder deeper waters, but that's not typically what happens. People get certified at Gullivers, then rent gear and head for Toby with an buddy of equal experience (or lack thereof).
I've buddied up with a few divers who certified at Gullivers or similar and now avoid diving with people who have, as I have not the training or patience to deal with them.
