Canada and the Double hose regulator

[Ron Hearn]

Hi

I was talking to a vintage diver at the Vancouver aquarium who told me that at one point in history that the first double hose regulators to hit the north American market were assembled in Canada. Is there any infomation that I can obtain about were/when this took place. I understnd that Emile Gagnan was a french Canadian from Quebec and this may have played a role in this decision.

Thanks

Ron
