Snowbird Day Counter

You need to track two separate thresholds. First, your provincial health coverage: Ontario OHIP allows up to 212 days abroad per year; BC MSP and Alberta AHCIP allow up to 183 days (6 months). Second, the US Substantial Presence Test for IRS purposes. The IRS counts days in the US over a 3-year formula: all days this year, plus 1/3 of days last year, plus 1/6 of days two years ago. If that total is 183 or more, you are considered a US tax resident for that year. This rarely catches Canadians who stay under 120 days/year, but can affect frequent snowbirds. The Closer Connection Exception (IRS Form 8840) protects most Canadians who meet the 183-day formula but maintain stronger ties to Canada.

If you exceed your provincial health plan's absence limit, you lose coverage. The practical consequence depends on when you discover it. If you are abroad without coverage and require medical care, you are personally liable for all medical costs — which can be catastrophic in the US (common US hospital bills for serious conditions: $50,000–$500,000+). When you return to your home province and re-register, most provinces impose a waiting period of up to 3 months before reinstating coverage. During this period, travel insurance or private health coverage is essential. Provincial health plans do not retroactively cancel — but they can audit your absence history and refuse to cover claims for periods when you exceeded the limit.

OHIP does not actively track departure and return dates in real time. However, when you make a claim — or when you apply for OHIP at renewal — you attest to your residency. OHIP can request evidence of Ontario residency during any given tax year, including flight records, credit card statements, utility bills, and property tax receipts. If you are making a claim for a medical episode that occurred while abroad, OHIP reviews the circumstances. In practice, most snowbirds who stay under the 212-day limit have no issues. The risk increases for those who regularly push close to the limit, or who have extended their stays and lost track of the count.

Ontario's OHIP rules allow the Director to approve absence exemptions in specific cases — primarily for medical treatment abroad that cannot be obtained in Ontario, or for compassionate circumstances. These approvals are not automatic and require application. For planned extended absences, the more reliable strategy is to manage within the 212-day limit. Ontario does have a provision for approved absences (for students, public servants posted abroad, etc.) that are not counted against the limit — but typical snowbird absences do not qualify for these exemptions.

No — Old Age Security and Canada Pension Plan are not affected by how many days you spend abroad, as long as you remain a Canadian tax resident. OAS and CPP continue to be paid regardless of where you reside in the world. However, if you sever Canadian tax residency (becoming a non-resident of Canada for tax purposes), OAS and CPP become subject to non-resident withholding tax — typically 25%, reduced to 15–20% under Canada's tax treaties with the destination country (15% with Mexico, 25% with most Caribbean and Central American countries that don't have treaties). Retaining Canadian tax residency — by maintaining your home, banking, and ties in Canada — protects your OAS/CPP from non-resident withholding and preserves access to provincial health coverage.

The day limits apply to total days absent from your home province per calendar year, not per trip. If you take two snowbird trips — January–March (90 days) and November–December (60 days) — your total is 150 days, well within any provincial limit. Where it gets complex: if you split residency between provinces, each province's health plan has its own eligibility rules. You can only be a resident of one province for health insurance purposes — typically the province where you have your primary home and spend the majority of your in-Canada time. Trying to maintain dual provincial health coverage is not possible; you must choose one primary province.

Travel insurance covers costs that your provincial health plan does not — particularly medical care abroad (which provincial plans cover poorly or not at all) and the gap period if you have exceeded your absence limit and lost coverage. Key interaction: many travel insurance policies contain a clause stating that the policy is secondary to government health coverage. If your OHIP or AHCIP has lapsed due to over-absence, the travel insurer may deny claims on the basis that you breached your provincial eligibility and are therefore uninsured — leaving the travel insurer as the primary (or sole) payer. Read your travel insurance policy carefully, particularly the government coverage confirmation clause. Some policies require you to confirm that you are currently eligible for provincial health coverage as a condition of the policy.
