Ozempic vs Wegovy vs Mounjaro in Canada: Which GLP-1 Is Right for You?
GLP-1 receptor agonists have transformed weight management medicine. In Canada, three medications dominate the conversation: Ozempic (semaglutide), Wegovy (semaglutide, higher dose), and Mounjaro (tirzepatide). Each works differently, costs differently, and suits different patients.
What Are GLP-1 Medications?
GLP-1 (glucagon-like peptide-1) receptor agonists mimic a gut hormone that regulates appetite, slows gastric emptying, and improves insulin sensitivity. Originally developed for type 2 diabetes, they've become the most effective pharmacological tool for weight loss ever approved.
Head-to-Head Comparison
| Medication | Active Ingredient | Approved For | Average Weight Loss | Monthly Cost (Canada) | Availability |
|---|---|---|---|---|---|
| Ozempic | Semaglutide 0.5–2mg | Type 2 diabetes (off-label for weight) | 10–15% body weight | $250–$350 | Available but supply-constrained |
| Wegovy | Semaglutide 2.4mg | Chronic weight management | 15–17% body weight | $350–$500 | Limited availability in Canada |
| Mounjaro | Tirzepatide | Type 2 diabetes (off-label for weight) | 20–22% body weight | $300–$450 | Available, growing supply |
Ozempic: The Most Prescribed
Ozempic was approved in Canada in 2018 for type 2 diabetes. It's widely prescribed off-label for weight management and is the most familiar name in the space. The once-weekly injection starts at 0.25mg and titrates up to 2mg.
Best for: People with type 2 diabetes or prediabetes who also want weight loss. Insurance coverage is more likely under a diabetes indication.
Downside: Supply shortages have been ongoing since 2022. Your pharmacy may not always have it in stock.
Wegovy: The Weight Loss Version
Wegovy is the same molecule as Ozempic (semaglutide) but at a higher dose (2.4mg) and specifically approved for chronic weight management in adults with a BMI over 30, or over 27 with a weight-related condition.
Best for: People whose primary goal is weight loss, not diabetes management. The higher dose produces more significant weight reduction.
Downside: Limited availability in Canada. Some provinces have it; others don't. Cost is higher and insurance coverage is inconsistent.
Mounjaro: The Dual-Action Option
Mounjaro (tirzepatide) is a dual GIP/GLP-1 agonist — it activates two gut hormone receptors instead of one. Clinical trials show it produces the greatest weight loss of the three, with some patients losing over 20% of body weight.
Best for: People who want maximum weight loss efficacy and haven't responded adequately to semaglutide-based medications.
Downside: Approved in Canada for type 2 diabetes only (as of 2024). Off-label prescribing for weight loss is possible but requires a willing physician.
How to Get a Prescription in BC
All three medications require a prescription in Canada. Options:
- Your family doctor — if you have one and they're comfortable prescribing GLP-1s
- Telehealth platforms — Oak Weight Loss, Felix Health, and other platforms can prescribe online after a brief consultation
- Obesity medicine specialists — for complex cases or when primary care isn't accessible
The online route is typically fastest. A consultation takes 15–20 minutes and you can have a prescription within 24–48 hours.
Cost and Insurance
BC PharmaCare covers Ozempic for type 2 diabetes under specific criteria. For weight loss without a diabetes diagnosis, most patients pay out of pocket. Extended health benefits vary — check your plan.
Telehealth platforms often include the consultation fee in a monthly subscription model, which can reduce the total cost compared to paying separately for a specialist visit plus pharmacy.
Bottom Line
- Ozempic: Most accessible, good for diabetes + weight loss, watch for supply issues
- Wegovy: Best if weight loss is the primary goal and you can access it
- Mounjaro: Highest efficacy, dual mechanism, growing availability
If you're starting out, Ozempic is the most practical entry point in BC. If you've tried it and want more, ask about Mounjaro.
