Wegovy Canada: Cost, Availability, and How it Compares to Ozempic

If you’ve been researching weight loss medications in Canada, you’ve likely come across both Wegovy and Ozempic. The two are closely related, as each contains the same active ingredient — semaglutide. However, Wegovy and Ozempic are not the same treatment.
Wegovy and Ozempic contain semaglutide, but their approved uses, doses and devices differ. The sections below explain Wegovy’s Canadian indications and why the products should not be substituted without advice.
In this article, we’ll cover everything you need to know about Wegovy in Canada, including how it works, how much it costs, insurance coverage, side effects, and when generic alternatives may become available. We also go into detail about the key differences between Ozempic vs Wegovy.

What Is Wegovy?

Wegovy contains semaglutide. Canadian indications include chronic weight management in eligible patients and reduction of non-fatal heart-attack risk in adults with established cardiovascular disease and BMI ≥27. Its specified MASH indication has conditional authorization and concerns non-cirrhotic MASH with moderate to advanced fibrosis; it is not a general fatty-liver indication.

Which Wegovy Pen Am I Using?

The Canadian monograph describes both single-use and multi-use pens. Follow the instructions for the exact product dispensed and ask your pharmacist to demonstrate it.

How Does Wegovy Work for Weight Loss?

Wegovy works through the same mechanisms as other semaglutide-based GLP-1 medications. If you’ve already read our guide to Ozempic, the science will be familiar, but here’s a brief overview.
Semaglutide (the key ingredient of Wegovy) mimics the GLP-1 hormone, which your body releases naturally after eating. GLP-1 plays several roles in appetite regulation, including:

• Slowing gastric emptying (meaning food stays in your stomach longer after a meal, helping you feel full).
• Acting on appetite centres in the brain to reduce hunger.
• Enhancing insulin secretion to help regulate blood sugar.

Wegovy can reduce appetite and food intake. People respond differently, and weight-management care should include an individualized treatment and follow-up plan.

How Much Weight Can You Lose on Wegovy?

The clinical evidence for Wegovy comes primarily from the STEP trial program, which was a series of large, randomized, placebo-controlled studies.
In the foundational STEP 1 trial, 1,961 adults without diabetes took Wegovy or a placebo for 68 weeks alongside lifestyle changes. The results were significant: participants on Wegovy lost an average of 14.9% of their body weight (compared to just 2.4% for those on placebo). In practical terms, that’s an average loss of roughly 15 kg (33 lbs).
Looking at specific weight loss outcomes from STEP 1:

• Approximately 86% of patients lost at least 5% of their body weight
• 69% lost at least 10% of their body weight
• About half lost 15% or more
• Roughly one in three participants lost at least 20% of their body weight

Do the Weight Loss Results from Wegovy Last?

In STEP 5, 304 adults were followed for 104 weeks. Average weight change was -15.2% with continued semaglutide treatment and -2.6% with placebo; both groups received behavioural support. These are group averages, not predictions for an individual.
However, obesity is a chronic metabolic condition, and research shows that stopping GLP-1 medications like Wegovy, Ozempic and Mounjaro can lead to significant weight regain. 

Weight Regain After Stopping Wegovy

The STEP 1 extension followed a subset of 327 participants after study medication and structured lifestyle support ended. One year later, participants previously taking semaglutide had regained about two-thirds of their earlier weight loss on average. Several cardiometabolic measures moved toward baseline.
A 2026 systematic review estimated average regain of about 0.8 kg per month after newer incretin treatments were stopped. Its model projected return to baseline weight at about 1.5 years. This pooled semaglutide and tirzepatide evidence; follow-up for these treatments did not extend beyond 52 weeks, so the longer-term estimate is a projection.
These findings support the medical consensus that Wegovy is designed as a long-term therapy, and also highlight the importance of having a comprehensive lifestyle change and maintenance plan in place.

Wegovy and Heart Health: The SELECT Trial

Perhaps the most important clinical development for Wegovy is the SELECT trial — a landmark study that goes beyond weight loss entirely.
The SELECT trial enrolled over 17,600 adults across 41 countries. These were non-diabetic patients who were overweight or obese and had established cardiovascular disease (such as a prior heart attack, stroke, or peripheral artery disease). 
In SELECT, the primary cardiovascular outcome occurred in 6.5% of semaglutide participants and 8.0% of placebo participants over an average 39.8 months of follow-up. That is a 20% relative reduction and a 1.5 percentage-point absolute difference. The trial composite and the Canadian labelled indication are distinct.

Potential Benefits of Wegovy Beyond Weight Loss 

The SELECT trial findings are particularly notable because the cardiovascular benefits appeared early in the trial, before participants had achieved their maximum weight loss. 
A prespecified SELECT analysis estimated that reduced waist circumference explained about one-third of the cardiovascular benefit. It did not establish which mechanisms explained the remainder.

Implications for Insurance Coverage

A reimbursement recommendation does not itself confirm your coverage. Check your exact product, prescribed use and authorization requirements with your insurer or provincial plan.

How Does Wegovy Compare With Ozempic?

Both contain semaglutide, but their approved uses, doses and devices differ. Do not substitute one for the other without advice from your prescriber and pharmacist. Results from separate trials are not a direct comparison of the two products.

How Much Does Wegovy Cost in Canada?

Ask your pharmacy for a current quote for your prescribed dose and supply, including dispensing fees. Confirm your insurer’s requirements and any manufacturer savings separately. A reimbursement recommendation does not itself confirm your coverage. A single national price or guaranteed copayment can be misleading.

Wegovy Dosing Schedule

Wegovy uses a gradual dose escalation over 16 weeks to help your body adjust and minimise side effects. The official dosing schedule works as follows:

• Weeks 1–4: 0.25 mg once weekly
• Weeks 5–8: 0.5 mg once weekly
• Weeks 9–12: 1.0 mg once weekly
• Weeks 13–16: 1.7 mg once weekly
• Week 17 onward: 2.4 mg once weekly (maintenance dose)

This is the usual escalation schedule, not a direction to increase your own dose. Your prescriber may delay escalation if treatment is not tolerated.

Inject Wegovy subcutaneously (under the skin) in your abdomen, thigh, or upper arm, and rotate the injection site each week. You can take your weekly dose on any day, at any time, with or without food.

What to Do If You Miss a Wegovy Dose

Follow the missed-dose instructions supplied with your medication. If you miss doses or are unsure when to restart, ask your pharmacist or prescriber before taking the next dose.

Side Effects of Wegovy

Like all GLP-1 receptor agonists, Wegovy’s most common side effects are gastrointestinal. In the STEP clinical trials, the most frequently reported issues were:

• Nausea (affecting approximately 44% of patients)
• Diarrhea (30%)
• Vomiting (25%)
• Constipation (24%)

These numbers can sound concerning at first glance, but context matters. 
Gastrointestinal effects are often mild or moderate and may be more noticeable during dose escalation. Contact your clinician if symptoms persist or make it difficult to eat or stay hydrated.

Tips for Managing Wegovy Side Effects

To reduce the likelihood of gastrointestinal discomfort, consider eating smaller, more frequent meals rather than large ones, avoiding greasy, fried, or heavily spiced foods (especially during dose increases), staying well hydrated, and eating slowly. These are the same strategies recommended for patients on Ozempic and Mounjaro.

Before Starting Treatment

Review your medical history, medicines and pregnancy plans before treatment. Do not use Wegovy during pregnancy or breastfeeding, or with a personal or family history of medullary thyroid carcinoma, MEN 2 or a serious allergy to its ingredients. Stop at least two months before a planned pregnancy. Do not combine it with another semaglutide or GLP-1 medicine. Seek urgent care for severe persistent abdominal pain or a serious allergic reaction.
