Before you start

OHIP-eligible immigration status
Ontario as your primary place of residence
Intention to be physically present in Ontario for at least 153 of your first 183 days
Original supporting documents — one from each of the three categories

Step-by-step

1
Assemble one document from each of the three required categories
You need proof of citizenship or OHIP-eligible immigration status, proof of Ontario residency, and proof of identity. The accepted-documents list is specific, and being one document short is the most common reason a trip to ServiceOntario is wasted.

2
Apply in person at a ServiceOntario centre
Applicants over 16 generally must apply in person; this is not an online transaction. Hamilton has several centres and the ones in Ancaster, Stoney Creek and Dundas are usually quicker than the downtown office.

3
Take the coverage immediately — do not buy three months of private insurance
Eligible applicants are covered from enrolment. The three-month wait was abolished in 2020 and a great deal of published advice, and word of mouth, never caught up. The photo card arrives by post afterwards; the coverage does not wait for it.

4
Register to be matched with a family doctor on day one
Ontario runs a provincial service matching people without a family physician to one taking patients. Register when you arrive rather than when you first need care — your position depends on when you joined, and the shortage is province-wide regardless of how many hospitals a city has.

5
Learn which hospital does what, because they are not interchangeable
Hamilton General is the regional trauma and cardiac centre, Juravinski is cancer, McMaster Children's covers paediatrics and maternity for a wide region, and St. Joseph's is a separate organisation with its own emergency department and a large mental health service. The nearest building is not always the right one, and it is worth knowing before you need it.

6
Arrange cover for what OHIP excludes
Prescription drugs for working-age adults, dental, vision and physiotherapy sit largely outside OHIP. Employer benefit plans normally fill these, which makes the benefits package a real part of a job offer — and in a hospital-dominated job market those plans are generally good.

Things most newcomers don’t know

There is no three-month wait, and newcomers still pay for private cover they do not need.

The waiting period was removed from the regulations in March 2020 and eligible residents are covered from enrolment. It is one of the most persistently mis-reported facts about moving to Ontario — older guides, relocation agents and friends who arrived before 2020 all describe the old rule. Three months of unnecessary travel insurance is a several-hundred-dollar mistake made on stale advice.

Living beside a large teaching hospital does not shorten the queue for a family doctor.

Hamilton has an unusual concentration of hospital beds because it serves a region stretching well beyond the city, and newcomers reasonably assume that translates into easy access to primary care. It does not — hospitals and family practice are different systems with different funding, and the Ontario family doctor shortage applies here as everywhere. Register for a match on arrival and use walk-in clinics and Health811 meanwhile.

Source: Ontario — find a family doctor or nurse practitioner

St. Joseph's and Hamilton Health Sciences are separate organisations, which confuses everyone.

Two hospital corporations, several campuses each, split by specialty rather than by geography. A referral to a specialist at one does not give you a record at the other, and the emergency departments are run by different bodies. Ask which corporation and which site, and keep your own copies of results — the assumption that 'the Hamilton hospital' is one system causes real appointment mix-ups.

There is a physical-presence test, and a long trip home in your first six months can cost you.

You are generally expected to be in Ontario for at least 153 of your first 183 days. Newcomers who go back to settle affairs, or take an extended visit after arriving, can put eligibility in question at exactly the point they are relying on it. If a long absence is unavoidable, understand the rule before you book.

Common mistakes to avoid

Buying three months of private cover on the basis of the abolished waiting period.
Turning up at ServiceOntario without one document from each of the three required categories.
Waiting until you are ill to register for a family doctor.
Going to the nearest hospital rather than the one that handles your problem.
Assuming prescriptions, dental and vision are covered — for working-age adults they largely are not.
Travelling extensively in your first six months and breaching the physical-presence expectation.
