Compounded semaglutide exists in Canada but it's a grey area. Under the Food and Drugs Act, pharmacies can compound medications that are commercially available only if there's a specific patient need (allergy to an excipient, custom dosing, etc.). "It's cheaper" is not a valid reason under Health Canada guidelines.
That said, enforcement is minimal. I know of at least two compounding pharmacies in Ontario doing semaglutide at about $150-180 CAD/month. They require a prescription. Quality-wise, one of them publishes Janoshik COAs on their website — showed 99.1% purity on the last batch.
NAPRA (National Association of Pharmacy Regulatory Authorities) released guidance in late 2025 suggesting provincial colleges of pharmacy should crack down. Ontario College of Pharmacists sent a warning letter to compounders in January. So the window may be closing here too, similar to Australia.
