I got an email from Leadnow recently and they used this phrase about Poilievre "flipping a kill switch" on the constitution. I usually trust their emails, but this is one of those instances where I wanted to double check this one. I copy pasted the phrase into a search engine and came across this video.

I wanted to ask: What are your thoughts on the notwithstanding clause? How should it be used exactly? How shouldn't it be used? Should it be used/exist at all?
