Converting the licence is quite straightforward - no mind games with the questions like you get with EASA. I can personally recommend the Central Helicopter Training Academy and Helicopters Canada in Ontario, Mountain View Helicopters in Calgary, and LR there as well, but there are others - it just depends on where you intend to do the training.
But it ultimately depends on immigration. If you plan to use your family as sponsors they need to be aware that they are liable for supporting you for ten years if you end up without work.
