Trudeau did adopt some of Trump’s lingo when addressing him –by his forename, as you point out–, using “big” several times and referring to some treaty they negotiated as a “deal”. He also slowed down, as if talking to someone with impaired understanding. Finally, Trudeau delivered this gem:
Now, it’s not in my habit to agree with the Wall Street Journal, but Donald, they point out that, even though you’re a very smart guy, this is a very dumb thing to do.

It was brilliant; out in plain sight for anyone with mild linguistic skills yet too subtle for the Trump base to grasp any of it.
As good as that would be and as much as I desire it, my impression is that too many of them are trapped in a disinformation bubble to realize what and who is actually causing their problems. Some might, like the former Republican who shot at Trump and the veteran who blew up a Cybertruck, if I understood their motivation correctly, but I doubt such incidents will ever reach the scale for Republicans to reverse their entrenched stance on gun ownership.
