St. Mary’s is located at the north west corner of Yonge Street and Major Mackenzie Drive in Richmond Hill.

There is ample parking. The entrance to the parking lot is on the north side of Major Mackenzie Drive about 10 metres (30 feet) west of Yonge Street, the very first driveway west of Yonge Street. Please watch out for vehicles coming the other way and make your turn carefully especially when coming from the east as visibility is poor and the driveway, although allowing two-way traffic, is quite narrow.

There is pedestrian access from Yonge Street. You may need to ring the bell on weekdays.

St. Mary’s is wheelchair accessible from Major Mackenzie Drive and the parking lot.
