Thank you for the question. It is an important one for clarifying, as I did yesterday, that a PAL won't be required to possess parts. As I explained, a PAL relieves someone of what would otherwise be a criminal act—possessing, for example, a firearm. A PAL allows you to do that, but that's because it would otherwise be an offence to possess a firearm in the absence of a PAL.
Nothing in the bill nor in the motions before the committee makes it an offence to possess a part without a PAL, so you don't need a PAL to possess a part.
