The way Transport Canada has already prepared some of the draft legislation seems fine to me. It depends on the operation that you are going to be doing and on what the need is. If you're going to be doing a complex commercial operation, then you would need a pilot permit somewhat similar to what I have, which is what we are doing right now in aviation. If you're just going to be doing a recreational portion, then you would need the basic information, something like a competency card.
It's a tiered approach. It depends on what you are going to be doing and on the UAV that you are going to be using. That's entirely possible.
