Newbie alert! Help me get into freediving?

[Morgan]

I've been an advanced Scuba diver for years, and instead of becoming bored, I'm more interested than ever in expanding my abilities.
Right now I have no desire to see how far I can go on a single breath, or in competition (but who knows, right?). But I can't help thinking that some freediving training or skill could not only be worthwhile, but also of benefit to the scuba diving that I do (which is primarily wreck diving/penetrating).
Am I wrong?

If I do get started with freediving, what kind of course should i take?
What can I expect to learn, and how long would it take?
Gear requirements?
Any courses available in the Vancouver BC area?

Thanks in advance for your replies!
