Please ask your pharmacist to fax your doctor a refill request of your medication. You may have refills that are not listed on your bottle. Please allow 5 days’ response time for renewals by fax. For some regular medications, your pharmacist may be able to advance you some doses if you are running out very soon. For urgent or same day refill requests, a 30$ fee will apply.


The nearest main intersection to TMC is Yonge Street and Centre Street in Thornhill. Our facility consists of 2 buildings, side by side, located on Centre Street one block north of John Street just west of Yonge Street.

Our main building is 18 Centre Street. Enter from the rear, facing the parking lot.

We are also seeing patients at the building next door 24 Centre Street, accessible from the same parking lot. The entrance is facing Centre Street. There is a ramp leading to the entrance also from the parking lot.

Parking at our office is for short-term use only. Parking is very limited during daytime hours.
