Just blowing insulation in a the wall here without informing building standards it a bit of a no-no, you can just do that in Canada?
Houses typically aren't of (mostly) brick construction. Much more like US stuff, timber frames sitting on top of a brick / concrete basement, lots of drywall etc. When you do external wall insulation it's (I'm mostly guessing here mind) like sticking stuff in a partition wall in the UK; if you want to take the insulation out, you can, by pulling the drywall down and taking it out.
Or you just knock the house down and start again.

Ah, gotcha.
Yeah that makes it a lot easier. We need repointing, Stormdry cream and finding an installer that would say "no" if they think it's a risk.
"knock the house down and start again" or insulation on the outside with ventilation with heat recapture (or you get all the mould) but that's 10-15K for our 1952 semi. cough

Here in Norn Ire even roofspace/loft insulation has to be inspected and signed off.
