It affects spending in the run up to the election, so it is effective from now, since it's already less than a year away. It's literally called the "Election Finances Act"...

It has been in effect since 2017, unless you're counting the short period between it being deemed unconstitutional and the time it took to execute section 33.

What do you mean what?

then increasing the period without a commensurate increase in the spending cap is clearly even worse, and now, because of the use of the notwithstanding clause, it's above legal challenge.

I am not sure "worse" explains the functional difference. It seems like you're getting caught up in your emotions again.

How are you seriously trying to spin this?

Must everything be so emotional to you? Can you not just explain things logically like a normal person?
