Cathedraltown is bordered on the north to Major Mackenzie Drive, on the south to Elgin Mills Road, on the west to Victoria Square Boulevard, and on the east to Highway 404.

The land occupied by Cathedraltown was originally farmland owned by Romandale Farms, a breeder and exhibitor of Holstein cows.

Stephen B. Roman, the late founder of Romandale Farms, built the Cathedral on land he donated.

In the early 2000s, his daughter, Helen Roman-Barber, working with Donald Buttress, Surveyor of the Fabric Emeritus of Westminster Abbey, developed the design concept for Cathedraltown, based on European cathedral towns.

[citation needed] Designed under the direction of Donald Buttress, Cathedraltown reflects the Regency and Georgian architecture that was popular in London in the late 18th an early 19th centuries.
