Doug Lippay said: "What about Canadians owning property in other countries? You would think that other jurisdictions might retaliate?"

1) The biggest target of such changes is China, and I can't buy property there.

2) Far more importantly, you should ask Canadians under 40 if they care about being unable to buy property in other countries. I'd bet a vast majority would be just fine with "retaliation" as they struggle to find shelter in their hometowns due to a haywire market that has been entirely engineered by government policies.
