As my friend Mr. Simms pointed out, this sticks on both the timeliness and non-partisan nature of the communications.
I would also raise a similar bill where we have departments, in that case, Elections Canada, already acting as if legislation had passed in order to prepare. You seem to concur that this is a good practice.
The problem comes when that legislation is still being debated, especially over contentious things: gun control, gun classification, the election rules. These are not casual things for Canadians. It can create an environment in which the federal agency starts to be perceived as biased and in favour of these changes rather than the one that enacts the changes.
Do you follow my logic?
