It won't last. Various "armpit" towns throughout Ontario are now unaffordable. North Bay, Timming, Peterborough, Thunder Bay: all of them were cheap, and fell to investor speculation-based increases.

I'd encourage other provinces to preemptively smack down speculation hard, now, before the problem metastasizes. Don't wait until GTA or GVA property investors have played Monopoly in your small town; do it now, even if it offends a few established property owners.
