STI testing in Canada for visitors and couples: what public health says

Summary: Canada's public health system offers confidential sexual health care, but access differs by province and by clinic, and visitors face different rules than residents. This guide, written on 10 November 2026, summarises what the Public Health Agency of Canada (PHAC) advises, how the clinics run by Toronto Public Health work as one example and what the United Kingdom's travel advice says about medical costs for visitors. It is general information, not medical advice: see a health professional for your own situation.

What the federal agency says

PHAC states that anyone who is sexually active can get a sexually transmitted infection (STI), wherever they are, and that the risk is higher with condomless sex, new partners, sex tourism and alcohol or drug use. The agency says the most effective protection is to avoid sex with a new partner and activities that exchange body fluids, and that condoms must be used consistently and correctly every time. It recommends dental dams for oral sex and carrying your own condoms and dental dams when you travel, because they may be hard to find or of poor quality at your destination. It adds that birth control other than condoms does not protect against STIs.

Vaccines and testing before travelling

PHAC advises consulting a health professional or travel clinic ideally about six weeks before you leave, and asking whether you should be tested or vaccinated for HPV, hepatitis A, hepatitis B and mpox. It also says to check with your local public health authority about eligibility for the mpox vaccine. For a couple, the simplest approach is to book a joint appointment before the trip, agree on a testing schedule and share results.

Symptoms and when to see someone

PHAC notes that symptoms can be mild or absent, and lists signs such as rashes, unusual discharge, sores, burning when urinating, swollen glands in the groin, flu-like symptoms and jaundice. It points out that syphilis may cause no visible symptoms but can still be passed on, and that untreated STIs can cause serious harm, including infertility, chronic liver disease, pregnancy complications and some cancers. If you think you may have an infection, or you had higher-risk activity even without symptoms, the agency advises seeing a health care provider and sharing your travel history. It advises partners to be tested and treated if one is diagnosed and not to have sex if you think you have an STI.

Toronto as an example: free, confidential clinics

Health care in Canada is run by the provinces and territories, so services differ. In Toronto, according to the city's page, Toronto Public Health runs sexual health clinics where services are free and confidential for eligible people and no referral or Ontario health card (OHIP) is required. The clinics offer testing and treatment for STIs and HIV, free condoms and lube, emergency contraception, pregnancy testing and some vaccines, including mpox, but not PrEP or PEP. Appointments are needed at the four main clinics, bookable online or on 416-338-1234, and people with no symptoms can use Easy Screen online booking. First-time clients may need a short phone intake. One clinic in North York offers limited walk-in hours on Tuesday afternoons with registration from 1 p.m. The page also lists closures around early November 2026, so confirm hours before you go.

Other options in Toronto, according to the same search results, include the Hassle Free Clinic on Gerrard Street East, which runs drop-in testing for people without symptoms and anonymous rapid HIV testing, and community health centres with first-come drop-in hours. Sexual Health Infoline Ontario (SHILO, 416-392-2437 or 1-800-668-2437) is a free, anonymous line that can refer you to clinics. We could not verify the clinics in other provinces, so check the provincial health ministry or the local public health unit.

Costs and insurance for visitors

This is where visitors differ from residents. The FCDO says that medical treatment in Canada can be very expensive and that there are no special arrangements for British visitors, and it advises travel insurance that covers local treatment and evacuation. Dual British-Canadian citizens may still have to pay if they do not meet provincial residency requirements for healthcare. A public clinic that is free for eligible people may not be free for everyone, so ask when you book whether there is a charge for visitors and whether the service needs a health card. Do not assume that a travel insurance policy covers routine sexual health testing; read the exclusions.

Preparing as a couple

• Talk about testing, boundaries and what you will do if either of you has symptoms.
• Bring your own condoms and lubricant.
• Keep a record of your vaccinations, including hepatitis B and HPV.
• Know the emergency number: 911.
• If you need urgent care, go to an emergency room or walk-in clinic, as the FCDO advises, and show your insurance details.
