To be fair, yes, Canada has the second-largest land mass on the planet. ~90% or more of that landmass is largely inhospitable for larger communities though, whether it’s the Canadian Shield and the fact we can’t grow any crops on that or dig through tough rocks, the Tundra and Arctic (where it is way too cold to grow anything, much less settle), vast distances of forests - it is a lot tougher to build infrastructure in most of Canada, leaving it pretty much to the places already with larger population sizes. And even then, most people are still choosing to go to the three cities and immediate outlying areas where the most economic influence and possible social connections are - Vancouver, Toronto, Montreal.
It would seem deceiving, given how large Canada is, but there are very few places outside of those major metro centres where people want to live, or can even live comfortable lives and be productive. Honestly, given how little good land is available in Canada, it would make far more sense to cut down on suburban developments and focus on higher-density, transit-minded communities. Single-family homes are way too inefficient for what we actually need, and having politicians and citizens who demonize quadplexes and other high density options do not help at all.
Confiscating their drugs, forcible confinement… you serious? They’ll just get more when they get the chance; they’re addicts, and there are markets for them to find drugs, there’s no easy way of stopping addicts from getting what they need. Confiscating or 24 hour confinement just ends the immediate risk of use, there’s no saying that won’t stop them from getting another hit by the next day (or even guarantee that they haven’t already used it by the time they’re confiscated / confined).
You’re advocating for punishing people effectively for being poor and addicted to drugs. That’s kind of a fucked up opinion, and opening SCSs does not mean you aren’t thinking of the children - it’s also keeping addicts off the streets and away from exposing that lifestyle to children, but on a more humane and practical level.
