Quality of training is excellent in Canada, depending on where you train of course. You can get mountain flying experience, external load, turbine time if you want to, all within your 100-odd hours of CPL training. And you will most likely fly with experienced real world instructors, not 300hr CFIs. The question you have to ask yourself is what you want to do with your new Canadian license.
- Fly back in Europe? Then what is involved in converting that license to EASA? How much would it cost, and would you have to fly dozens or hundreds more hours to get to the EASA CPL minimum requirements?
- Fly in Canada? Then do you have a work permit or a viable way to get one?
