Medicines regulator in Canada
Are semaglutide and tirzepatide approved in Canada?
In Canada, semaglutide and tirzepatide products are prescription drugs authorised by Health Canada. Health Canada’s Drug Product Database lists every authorised product, its brand name and the uses it is approved for, which is the simplest way to confirm a product is legitimate.
Provinces and territories decide public drug plan coverage, and private insurance plans set their own rules, so coverage for weight management can differ from coverage for diabetes.
Who can prescribe weight loss medicines in Canada
Physicians and nurse practitioners can prescribe these medicines, and some provinces give limited prescribing rights to other professionals. Provincial and territorial regulatory colleges license practitioners and set rules for virtual care, so the prescriber should be licensed where you live.
Each college publishes a public register of its members, which you can use to check a prescriber’s name and licence.
Advertising and online offers
Canada restricts advertising of prescription drugs to the public. Adverts that make claims about what a named prescription weight loss drug will do for you should be treated with caution.
Fake and unlicensed products
The World Health Organization has issued alerts about falsified semaglutide pens found in several regions. Falsified products may contain the wrong ingredient, the wrong amount or something harmful, and can look very similar to the real packaging.
Safer habits: get the medicine from a licensed pharmacy with a prescription, check the packaging and batch details, never buy from a social media seller, and report suspected fakes to Health Canada.
Botox, fillers and medical aesthetics in Canada
Botulinum toxin products are prescription drugs authorised by Health Canada, and dermal fillers are licensed as medical devices. Provincial colleges decide which professionals may inject and under what supervision.

Frequently asked questions
Do I need a prescription for semaglutide or tirzepatide in Canada?
Yes. Both are prescription-only medicines in Canada, so a registered prescriber has to assess you first.
Is it safe to buy weight loss injections online in Canada?
Only from a licensed pharmacy with a valid prescription. Falsified semaglutide pens have been found by regulators, and sellers on social media or websites that skip the prescription are the most common source of them.
What is the difference between semaglutide and tirzepatide?
Semaglutide acts on the GLP-1 hormone receptor. Tirzepatide acts on two receptors, GIP and GLP-1. Both are weekly injections that affect appetite and blood sugar, and a prescriber decides which, if either, is suitable for you.
Can a medical spa in Canada offer GLP-1 weight loss?
Some medical spas and aesthetic clinics run weight management programs with a licensed prescriber. Whether that is allowed, and who must be involved, depends on the rules in Canada. Ask who prescribes and who follows you up.
Who regulates Botox and fillers in Canada?
Health Canada oversees medicines and medical products in Canada. Professional councils decide which practitioners may inject, so check both the product and the practitioner.
