I'M A CANADIAN CITIZEN, my wife is from Luxembourg.Need more information. Where is your wife from? Are you a Canadian citizen or PR?
She can't just get OHIP. When you get OHIP depends on whether you apply inland or outland. For outland you are eligible for OHIP 90 days after you land as a PR. For inland it is at the Approval in Principle stage, which is closer to the end of the process (which takes about 12 months).
