If you've been researching semaglutide in Canada, you've probably noticed two brand names that keep appearing: Ozempic and Wegovy. They contain the exact same active ingredient. They're made by the same company. Yet they have different Health Canada approvals, different dosing schedules, and very different insurance situations.
I've spent months talking to Canadian patients, pharmacists, and doctors about these two medications. This guide breaks down everything you need to know so you can have an informed conversation with your prescriber.

How Ozempic Works
Ozempic (semaglutide) is a GLP-1 receptor agonist approved by Health Canada for type 2 diabetes. It mimics the incretin hormone GLP-1, which your gut naturally releases after eating. This triggers insulin secretion, slows gastric emptying, and reduces appetite.
Ozempic comes in three dose strengths: 0.25 mg (starter), 0.5 mg, and 1 mg, with a 2 mg option added in 2022. Patients typically start at 0.25 mg for four weeks, then step up. Most people stabilize at 0.5 mg or 1 mg.
While Ozempic is officially a diabetes drug, many Canadian doctors prescribe it off-label for weight loss. This is legal and common, but it means insurance usually won't cover it unless you also have a diabetes diagnosis.
How Wegovy Works
Wegovy is the same molecule as Ozempic, but it was developed and approved specifically for chronic weight management. Health Canada approved Wegovy in 2022 for adults with a BMI of 30 or higher, or 27 or higher with at least one weight-related comorbidity.
The dosing schedule is more aggressive than Ozempic. Wegovy escalates from 0.25 mg through 0.5 mg, 1 mg, and 1.7 mg before reaching the maintenance dose of 2.4 mg per week. That top dose is 20% higher than Ozempic's maximum, which is one reason Wegovy tends to produce greater weight loss.
Availability has been a problem since launch. Novo Nordisk has faced persistent supply constraints in Canada. As of early 2026, Wegovy is becoming more consistently available at Canadian pharmacies, but you should check stock before assuming you can fill a prescription.
Weight Loss Results
Clinical trial data gives us a good picture of what to expect from each medication.
Ozempic (SUSTAIN trials): Participants lost an average of 9.9% to 12.4% of body weight at the 1 mg dose over 68 weeks. At the 2 mg dose, results were closer to 15%.
Wegovy (STEP trials): At the 2.4 mg maintenance dose, participants lost an average of 14.9% of body weight over 68 weeks. Some participants in the STEP 1 trial lost over 20%. The SELECT cardiovascular outcomes trial also showed a 20% reduction in major cardiovascular events.
The difference comes down to dose. Wegovy's 2.4 mg maintenance dose simply provides more semaglutide than Ozempic's standard 1 mg. If your doctor prescribes Ozempic at 2 mg off-label, the gap narrows significantly.
Cost in Canada
Cost is where these two medications diverge sharply for most Canadians.
| Cost Factor | Ozempic | Wegovy |
| --- | --- | --- |
| Monthly retail (no insurance) | $250-$340 | $400-$500 |
| Annual cost | $3,000-$4,080 | $4,800-$6,000 |
| Provincial formulary | Most provinces for T2D | Not listed in most provinces |
| Private insurance | Commonly covered for diabetes | Growing but inconsistent |
| Manufacturer savings | Novo Nordisk patient support | Novo Nordisk patient support |
Ozempic is significantly cheaper, mainly because it has been on the market longer and is listed on most provincial formularies for type 2 diabetes. Wegovy, being newer and approved for weight management rather than diabetes, faces more coverage barriers.
Generic Semaglutide at In-Person Canadian Pharmacies
Cash retail prices for generic semaglutide at Canadian pharmacies are now coming in below the telehealth alternatives, based on early Canadian consumer reports. Costco Pharmacy is the lowest reliable option at roughly $88 to $99 per month (confirmed pickups: $88.88 GTA, $88 Ontario, $99 Laval, $91 Medicine Hat). Walmart and Loblaws No Frills typically come in around $95 to $110 per month. Shoppers Drug Mart, Rexall and London Drugs are running roughly $100 to $120 per month (one Halifax-area Shoppers fill reported $113 for the 0.25mg starter dose). Apotex's Apo-Semaglutide Injection began shipping to Canadian pharmacies on May 20, 2026, with Dr. Reddy's generic also launching in May 2026.
That makes in-person pharmacies — especially Costco — meaningfully cheaper than telehealth providers for generic semaglutide. Felix Health and Hims Canada both list $149 per month all-in for the same generic Apo-Semaglutide on their public pricing pages. For most Canadians with a valid prescription, walking it into a local pharmacy is now the cheapest reliable path.
Pricing context: per the Globe and Mail, Apotex's published wholesale price is $78.14 for a four-week supply — roughly one-third of brand-name Ozempic's $240.48 wholesale price. Retail estimates above reflect that wholesale plus each chain's standard dispensing fee and markup. See also coverage from CBC News on the Canadian launch. Note: The May 2026 generic launch covers the Ozempic indication for type 2 diabetes only. Generic Wegovy (semaglutide 2.4 mg for chronic weight management) is not yet available — Novo Nordisk holds additional patents on the high-dose formulation. Under the pan-Canadian Pharmaceutical Alliance framework, the maximum public drug plan price for generic semaglutide is approximately $114 per four-week supply with two manufacturers approved, dropping to roughly $80 once a third manufacturer launches.
Side Effects Comparison
Since Ozempic and Wegovy contain the same molecule, their side effect profiles are nearly identical. The most common issues are gastrointestinal:
- Nausea (reported by 15-20% of users in trials)
- Diarrhea
- Constipation
- Abdominal pain
- Injection site reactions
Wegovy users may experience slightly more intense GI side effects because of the higher maintenance dose. The escalation schedule helps minimize this, but the jump from 1.7 mg to 2.4 mg is where many patients feel it most.
Rare but serious risks for both medications include pancreatitis, gallbladder problems, and a theoretical risk of medullary thyroid carcinoma (based on animal studies). Both carry the same boxed warning about thyroid C-cell tumors.
Insurance and Coverage
This is where the biggest practical difference lies for most Canadians.
Ozempic is listed on provincial formularies across Canada for type 2 diabetes. Ontario, Quebec, BC, Alberta, and most other provinces cover it through public drug plans for patients with a confirmed diabetes diagnosis. Most private employer insurance plans also cover Ozempic for diabetes.
Wegovy is not on most provincial formularies as of early 2026. Quebec was among the first to add it. Some private insurance plans have started covering Wegovy, particularly after the SELECT trial demonstrated cardiovascular benefits. However, many plans still exclude weight management drugs entirely.
If your goal is weight loss and you don't have type 2 diabetes, getting insurance to cover either medication is a challenge. Some patients work with their doctors to document weight-related comorbidities like sleep apnea or hypertension, which can help with special authorization requests.
Which Should You Choose?
The answer depends on your situation:
Choose Ozempic if: You have type 2 diabetes and want weight loss as a secondary benefit. Insurance coverage will be much easier to obtain, and the cost out of pocket is lower.
Choose Wegovy if: Weight management is your primary goal, you don't have diabetes, and you either have insurance that covers it or can afford to pay out of pocket. The 2.4 mg dose is optimized for weight loss.
Many Canadians end up on Ozempic even when weight loss is the goal, simply because it is more accessible and affordable. Since May 2026, generic semaglutide has made the Ozempic option cheaper still, about $88 to $99 per month at Costco Pharmacy. Your doctor can help you weigh the trade-offs based on your health profile.

Frequently Asked Questions
Can I switch from Ozempic to Wegovy?
Yes. Since both are semaglutide, switching is straightforward. Your doctor will typically match your current Ozempic dose to the equivalent Wegovy dose and continue the escalation from there. You won't need to start over at 0.25 mg.
Is Wegovy stronger than Ozempic?
Not stronger per se. Wegovy reaches a higher maximum dose (2.4 mg vs. Ozempic's standard 1 mg or optional 2 mg). The molecule itself is identical. The higher dose drives more weight loss on average.
Can my doctor prescribe Ozempic for weight loss?
Yes. Off-label prescribing is legal and common in Canada. However, insurance may not cover it for this use, meaning you'd likely pay out of pocket. Many telehealth platforms in Canada, such as Felix and Maple, offer weight loss consultations that can lead to an Ozempic prescription.
Will Wegovy get cheaper in Canada?
Two things are in play. As more provinces add Wegovy to their formularies and supply stabilizes, brand prices may ease. And since the May 2026 launch of generic semaglutide (Dr. Reddy's and Apotex), Ozempic-equivalent doses now retail as low as $88 to $99 per month at Costco Pharmacy and roughly $100 to $120 at most other chains. Generic Wegovy (2.4 mg) remains years away because of additional Novo Nordisk patents on the high-dose formulation and weight-management indication.
