I might be able to offer something in that respect.
The vast majority of these types of provisions--I'm creating a basket for ones that I didn't deal with, basically--are quite common in respect of Canada's import-related and taxation-related statutes. I believe they are repeated for good purpose.
However, insofar as clause 75 is concerned, the last phrase there is peculiar, and I suspect, although there are probably people in a better position than I right this moment, that it relates in part to the retroactive nature of this proposed legislation. It hasn't received assent, and I suspect that if activities even today were such that someone had already committed an offence per se, it may have been written in language such that, whether or not the person has been prosecuted or convicted, it would cover off the potential retroactivity.
That's the best I can do. That phrase is a little odd, but it may relate to the somewhat odd approach that has been taken with the promulgation of the bill.
In that respect I have a very brief comment. A lot of the things I have spoken about might have been looked after and been less contentious if they had begun with promulgation of policy and regulations to support the bill. Unfortunately, you're not at that stage. It has been done in reverse.
