OK, I hear you, I do. You say you want to cut off.
At least, that's what you think you want. Is it possible this is an over-reaction?
You say you want out of the concrete jungle. That seems more plausible.
You're in Canada, so I'm guessing GTA or Vancouver?
Before heading "up north" (if you haven't been, you have no idea, sorry - don't mean to patronize, but you don't - one doesn't just "go up north" without having visited with competent guides), why not head out of town for a bit? If you are GTA, why not Perth or Smith's Falls or Arnprior? (Yeah, these are more my neck of the woods, but you need to get far from your neck to get to the woods, know what I mean?)
Consider a change of pace, before considering a harsh and radical cut off. Maybe some place that still has running water and electricity and where the amenities of civilization are only 1-3 hours away by car.
Rent a farm north of Bancroft, near Algonquin. Someplace rural but with folks not so far away. Close enough but not too far, you know?
You want even more remote, but still sort of civilized? How about Fermont, QC? (Last spot before Labrador, road pretty much ends there.)
If you're not GTA, folks from your neck of the woods can suggest places comparable to the above....
(I moved to T.O. after university - small place out east - and I hated the jungle, it went on forever. Moved to Ottawa after a couple of years. Been here over 23. It's grown, but it's way less jungle than the GTA. I'm in the burbs, I can be on a farm in 5 minutes and not see anyone for miles....)
Heck, why not just go canoeing in Algonquin for a week? A buddy of mine unplugs that way for a week every year - keeps him sane, and it's a less radical prescription.
