Ozempic and GLP-1 drug supply in Canada

No drug class strained the Canadian supply chain quite like the GLP-1 receptor agonists. Between 2022 and 2024, demand for Ozempic (semaglutide) grew faster than any manufacturer could build capacity, and Health Canada issued repeated notices about intermittent shortages. Supply of the class has since stabilized, but individual doses and pens still run short at individual pharmacies, and the arrival of generic semaglutide in 2026 has reshuffled demand again, with pharmacies in some provinces reporting they cannot keep generic versions on the shelf.

Why this class is different

GLP-1 drugs are injectables made on specialized production lines, and pens for different doses are separate products with separate supply chains. That is why a pharmacy can have the 1 mg pen and be out of the 0.5 mg starter dose for weeks. On rxstat, each strength appears as its own product line on the semaglutide page, so you can see exactly which doses have active reports rather than a single vague status for the whole brand.

Generics changed the picture

Canada was one of the first major markets where semaglutide patents opened up, and generic versions began arriving in 2026 at substantially lower prices. Lower prices widened access, which added demand, and generic makers have had their own supply wobbles while ramping up. If your pharmacy is out of the generic, ask two questions: whether the brand version is in stock (it often is), and whether your insurer requires the generic or will cover the brand at a difference in cost. A pharmacist can dispense the brand against a prescription written generically.

If your dose is unavailable

Do not stretch doses or skip weeks without advice; consistency matters for both diabetes control and weight management, and abrupt gaps can undo months of progress. Pharmacists can check distributor stock, transfer your prescription to a location that has your dose, and in some cases bridge you with an equivalent dose combination. If nothing in the molecule is available, a prescriber can consider another drug in the class, since several GLP-1 and dual-agonist options now exist in Canada, each with its own supply situation you can check here before the appointment.

One caution: when legitimate supply tightens, counterfeit "Ozempic" appears online. Only buy from a licensed Canadian pharmacy, and treat any site selling it without a prescription as fraudulent.
