Good post. Poilievre is following the playbook of demagogues everywhere: Rant vociferously about "freedoms" being taken and the high cost of living and then be vague on what would be done because of incompetence and fear of giving the opposition something to sink their teeth into.

Perhaps the phrase needed is instead something with more bite than "euphemism" (which after all serves a useful social function). Your first synonym "code word" is applicable, as is "dog whistle". Perhaps something like "misdirections" (oo - shiny loss of freedom over there!), "cover story" (block some subsidies while massively cutting taxes and pushing into deficit), etc.

Others that I found looking up synonyms were:

chicanery
subtefuge
devious
shady
tricky
hypocrisy
deception
deceit
sneaky words
sly words

He avoids debates because he can't afford to be pinned down on his bullshit. Maybe that's the key; couple a word indicating deception with "bullshit":

devious bull or devious bullshit
tricky bullshit
sly bullshit
sneaky bullshit
hypocritical bullshit

It looks like we'll be stuck with him for a while.

Better put the media on notice that if they soft-pedal his sly bullshit like the media in the US soft-pedalled tRump's hypocritical bullshit, then we are in danger of ending up with a bilingual tRumpish disaster here.
