Perhaps the biggest difference between German/French/Swiss/etc hiking and the Canadian Rockies is the much lower density of human development. You will be out of cell phone range most of the time, and there are many fewer backcountry developments such as chalets, huts, shelters and footbridges.
If you stick to popular routes inside the national parks, you probably do not need a GPS or a emergency beacon, although I think they're still good ideas. Those areas are well covered by good maps and you will encounter other hikers should an emergency arise. I doubt that you would ever need a satellite phone. You must always manage your food supply with bears in mind which means hanging your food high out of reach, or using a bearproof canister stashed a good distance downwind. You can find exhaustive information about these and other topics on the Parks Canada website.
As Kokanee75 said, you can get better advice once you have a destination in mind. Many European travelers have posted here to inquire about destinations, so it would probably be worthwhile to check out past responses. Be aware that if you ask for recommendations, you will receive 100 responses with 300 opinions, and you will not have gained much. Much better to study destinations online, narrow down to a few and ask specific questions.
