As obesity rates continue to rise across North America, more Canadians are seeking effective weight loss solutions. Semaglutide, marketed under brand names like Ozempic and Wegovy, has emerged as a groundbreaking medication for weight management. But with changing regulations and varying availability, many wonder about its legal status in Canada as we move into 2025.

What is Semaglutide and How Does it Work?

Semaglutide belongs to a class of medications called GLP-1 receptor agonists. Originally developed for type 2 diabetes, it works by mimicking a hormone that targets areas of the brain regulating appetite and food intake. The medication helps users feel fuller longer, naturally reducing caloric intake and promoting weight loss. When used alongside lifestyle modifications, semaglutide has shown impressive results, with many users experiencing 15-20% weight reduction over time.

Legal Status of Semaglutide in Canada in 2025

Semaglutide is legal in Canada for both diabetes management and weight loss in 2025. Health Canada first approved Ozempic (semaglutide) for type 2 diabetes in 2018. Later, in 2021, Wegovy (a higher-dose semaglutide formulation specifically for weight management) received approval for chronic weight management in adults with obesity or overweight with at least one weight-related comorbidity.

As of 2025, these approvals remain in place, though specific prescribing guidelines have evolved to address supply challenges and ensure appropriate patient selection.

Prescription Requirements and Access

To legally obtain semaglutide in Canada, patients must:

1. Consult with a licensed healthcare provider

2. Meet clinical criteria for prescription (typically having a BMI ≥30, or ≥27 with weight-related complications)

3. Obtain a valid prescription

4. Fill the prescription at a registered Canadian pharmacy

It’s important to note that off-label prescribing of Ozempic specifically for weight loss (rather than using Wegovy) has become more regulated since 2023 due to supply shortages affecting diabetes patients. Current regulations prioritize Ozempic access for those with diabetes while directing weight management patients toward Wegovy.

Insurance Coverage and Cost in 2025

The financial landscape for semaglutide has evolved significantly by 2025. Several provincial health plans now provide coverage for Wegovy in cases of clinical obesity with complications, though specific eligibility criteria vary by province. Many private insurance plans have also expanded coverage, recognizing the long-term cost benefits of effective weight management.

Without insurance, monthly costs for Wegovy typically range from $300-400 CAD, though patient assistance programs remain available. This represents a modest decrease from earlier pricing, reflecting increased competition in the GLP-1 market.

Safety Considerations and Side Effects

While legally available, semaglutide isn’t appropriate for everyone. Common side effects include nausea, vomiting, diarrhea, and constipation. These typically improve over time as the body adjusts to the medication.

More serious but rare side effects can include pancreatitis, gallbladder problems, and kidney issues. Canadian prescribing guidelines now emphasize thorough screening for contraindications, including personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2.

Compounded Semaglutide: Legal but Regulated

With demand outpacing supply in recent years, some have turned to compounding pharmacies for semaglutide. As of 2025, compounded semaglutide is legal in Canada under specific conditions:

1. It must be prescribed by a licensed healthcare provider

2. The compounding must be performed by a licensed pharmacy

3. The compounding must follow Health Canada’s guidelines for pharmaceutical compounding

4. It must be for individual patient use (not mass production)

However, Health Canada has strengthened oversight of compounded semaglutide, requiring additional quality testing and patient disclosures about the differences between compounded and commercially manufactured products.

Online Purchases and Importation

Purchasing semaglutide online without a valid Canadian prescription remains illegal and potentially dangerous. The rise in counterfeit weight loss medications has prompted increased border screening and enforcement actions by Health Canada.

Personal importation rules permit Canadians to bring up to a 90-day supply of prescription medication for personal use when traveling, provided they have a valid prescription. However, ordering from international pharmacies without Canadian medical oversight is not recommended and may violate multiple regulations.

The Future of Semaglutide in Canada

Looking ahead, Canada is expected to approve additional GLP-1 medications for weight management by late 2025, potentially improving access and affordability. Clinical guidelines continue to evolve, with a growing emphasis on identifying patients most likely to benefit from these medications and supporting long-term treatment adherence.

Research into combination therapies and improved formulations continues, with Canadian researchers playing a significant role in several international clinical trials.

Conclusion

Semaglutide remains legal for weight loss in Canada in 2025, with a more mature regulatory framework that balances access, safety, and appropriate use. For Canadians struggling with obesity, this medication represents an important treatment option, though it works best as part of a comprehensive approach that includes dietary changes, physical activity, and behavioral support.

If you’re considering semaglutide for weight management, consult with a healthcare provider to discuss whether it’s appropriate for your specific health situation, and to ensure you’re accessing it through legal, safe channels.
