I do know that people have transacted real estate in Bitcoin in Canada before, mostly as a gimmick, but no reason you couldn't do that legally on the Canadian end. But I assume one would convert to CAD. What's the problem with KYC on the Canadian bank end? Canada has no such controls and wouldn't care that the money was laundered out of Argentina.

Even if you had to do that, laundering the funds into Canada unfortunately does not seem it would be difficult in practice, given the apparent scale of money-laundering associated with the Vancouver housing market. And you do not have to be physically present to acquire property in Canada.
