Ontario health coverage residency rules
What residents of Ontario need to know about OHIP coverage, what they stand to lose if they cross the absence threshold, and how the rolling-12-month math actually works.
The rule, in plain English
OHIP requires you to be physically present in Ontario at least 153 days in any rolling 12-month window. You may be absent up to 212 days without prior approval.
On return, the wait period before coverage resumes is zero — coverage starts same day as application approval. Ontario eliminated the 3-month OHIP wait during COVID and never reinstated it. Coverage begins same day as approval for both new and returning residents. U of T paperwork still references the old 3-month wait — students should apply OHIP day 1 and walk approval to UHIP office to opt out, saving ~$200/term.
What you stand to lose
If you fall below the residency threshold without an approved extended-absence application, you lose access to the following programs and credits. These are the marquee items most Ontario residents do not realize are tied to provincial residency.
