The content of the throne speech will be designed to make the opposition trigger a non-confidence vote

And the opposition will be wise enough not to take the bait. Remember, they can have a confidence vote any time they want. There's no need to do it on Trudeau's terms.

the Liberals and their media pawns will spin it as the opposition trying to "divide" the country with the intent of people eating up (combined with the CERB high) which will translate to voters voting for them en masse.

That's probably their plan, but again I don't think the opposition will take the bait. I mean why would the opposition trigger an election when Trudeau is still enjoying a major covid bump, and before the whole WE scandal has been allowed to run its course. At the very least, the CPC will wait until that one run its course.

Edit: Oh wait. Seems Trudeau's approval/disapproval rates flipped two weeks ago and the media never reported it.
