What does MSW RSW mean in Canada?

If you’ve ever looked at your insurance benefits or browsed a therapist’s profile and come across the term MSW, RSW (either together or separate) you might have wondered: what do these letters actually mean?

You’re not alone. MSW and RSW are two of the most common credentials listed by therapists in Canada, but they’re rarely explained. And when it comes to finding the right therapist, and understanding what’s covered by your insurance plan, the details matter.

Let’s break it down—clearly and simply.

What does MSW stand for?

MSW stands for Master of Social Work. It’s a graduate-level degree earned after completing a Bachelor’s degree.

MSWs don't always practice psychotherapy. There are many MSWs who work in healthcare or public services which don't include therapy.

However, a therapist with an MSW has specialized training in areas like mental health, trauma, relationships, family systems, and counselling. It’s one of the most common degrees held by therapists in Canada.

Why does this matter to you? Most extended health insurance plans that include mental health benefits will cover therapy sessions with someone who holds an MSW—if they’re also registered. That second part is key.

MSWs are not medical professionals, which means they can’t prescribe medication or make formal mental health diagnoses. But they’re trained to recognize when someone might benefit from additional support, and they can refer clients to psychiatrists or doctors when needed.

What does RSW stand for?

RSW means Registered Social Worker. This tells you that the therapist is licensed with a provincial college—like the Ontario College of Social Workers and Social Service Workers (OCSWSSW) or the BC College of Social Workers.

Registration is more than a formality. It means the therapist:

• Has met the education and training requirements
• Follows a code of ethics and professional standards
• Participates in continuing education
• Is accountable to a regulatory body

If you ever have a concern about the therapist’s conduct or professionalism, their college is who you would contact.

Why do I often see MSW, RSW together?

In Canada, therapists who are social workers typically include both designations in their bios: MSW refers to their education; RSW refers to their registration.

Together, “MSW, RSW” tells you this person has both the academic training and the professional license required to practice therapy as a social worker.

Many insurance providers will only reimburse therapy if the provider is both a registered social worker and has a Master’s degree—so MSW, RSW is the combination to look for.

What if my insurance only lists “MSW”?

This is where it can get a bit confusing. Some benefit plans simply list “MSW” under eligible providers, but in practice, most insurers require that the person also be registered (i.e. a RSW, too).

That means even if your plan says “MSW,” they will likely still expect the therapist to be an RSW.

Can an Social Workers practice psychotherapy?

Yes. Across most of Canada, social workers are legally allowed to provide psychotherapy services.

In provinces like Ontario and Quebec, psychotherapy is a controlled act, which means only professionals registered with specific colleges can offer it. MSW RSWs are included in that group. In Ontario, for example, RSWs are permitted to call themselves "Psychotherapists" when they also include "Registered Social Worker" the college name, or "MSW RSW"

Keep in mind that “psychotherapy” is just one term under the therapy umbrella. You might also see terms like “counselling” or “talk therapy” used interchangeably. If you want to understand the differences across therapy titles, check out our comparison of therapist designations in Canada.

Can someone be an RSW without an MSW?

Yes. Some social workers hold a Bachelor of Social Work (BSW) rather than a Master’s degree. They can still be registered as an RSW and may offer counselling services, depending on their scope of practice, training, and experience.

Whether your insurance covers a BSW RSW depends on your specific plan—some do, others don’t. Again, it’s worth asking your provider.

Can someone have an MSW without being an RSW?

Also yes. A person might hold an MSW but choose not to register with their provincial college.

Some MSWs work in research, policy, education, or other non-clinical roles and don’t need to be registered. But if someone is offering therapy and billing under insurance, they must be registered to qualify.

Who regulates social workers in Canada?

Each province and territory has its own college that licenses and oversees social workers. These colleges exist to protect the public and ensure ethical, competent practice.

Here are a few examples:

• Ontario College of Social Workers and Social Service Workers
• British Columbia College of Social Workers
• Alberta College of Social Workers
• Ordre des travailleurs sociaux et des thérapeutes conjugaux et familiaux du Québec

You can verify any therapist’s registration status on their college’s public directory on their website.

How do I find a therapist who is an MSW, RSW?

The easiest way is to look for those letters—MSW, RSW—listed under the therapist’s credentials. On First Session, you can filter by designation, browse bios, and even watch videos to get a sense of the therapist’s style and approach. If you're unsure about the MSW part, ensure to check your providers education section for "Masters of Social Work".

If you’re using insurance, it’s always a good idea to double-check that your provider covers MSW RSWs.

MSW, RSW might look like a flashy business card at first—but once you understand what each part means, it becomes a helpful shorthand for identifying a trained, licensed, and often insurance-eligible therapist.

Of course, social workers aren’t the only professionals who provide therapy in Canada. Here’s how they compare to psychologists, psychotherapists, and psychiatrists.

At the end of the day, your relationship with your therapist matters most. Credentials are just the starting point. The right fit can make all the difference.
