Grimsby Medical Associates is a medical clinic located in the Town of Grimsby, Ontario. Our team approach links your family doctor with other health care team providers to give you the best possible care. The focus is on keeping you and your family healthy, not just treating you when you are sick.

Your care team consists of many members:

Family Doctor; Family Medicine Residents; Nursing Team; Administrative Team; Mental Health Team; Chronic Disease Team, Geriatric Team and Diabetic Team

Each of these health care workers plays a different role in your health care so you and your family can benefit from a well-rounded approach to health.


Grimsby Medical Associates has partnered with PatientServe to collect NON-OHIP covered fees . 

Patients will receive a letter in the mail with registration material so they can register with PatientServe .  Patients will have the option of paying online using the PatientServe website.

 COVID Information and Updates :

Dear Patients,
A long 22 months ago, under the guidance of the Ontario Ministry of Health, we shifted to a Virtual First approach for appointments. As a result of the sacrifices and hard work by everyone to keep us all safe, and the tremendous strides made through vaccination efforts, we think we are making our way out of this pandemic.
In response, we are pleased to let you know we are moving away from the Virtual First approach and
providing more in-person appointments. We will continue when appropriate to offer virtual
appointments. To allow for more in-person care, we are keeping our clinic capacity at a number that still allows for physical distancing and maintaining other safety protocols, including regular disinfection.
If you are coming for an in-person visit, please remember to wear a mask to your appointment and
complete the self-screening for COVID ( https://covid19.ontario.ca/self-assessment/.)
If you or your family member have symptoms of COVID  and you would like medical advice, please call us.

We can discuss what the options are for care including:

• Providing care through a virtual appointment
• Being seen in-person in our office
• If emergency care is needed (for example, if you are having difficulty breathing or experiencing
other severe symptoms).

Please note that you do not require a medical note or proof of a negative test for clearance to return to school or work.
We are grateful for your patience as we work to balance the need for in-person medical care with the need to keep everyone safe as part of our new normal. We remain open to care for you.
