St. Marys

St. Marys is a town in southwestern Ontario, Canada. It is located at the confluence of the north branch of the Thames River and Trout Creek southwest of Stratford, and is surrounded by the Township of Perth South in Perth County, Ontario. St. Marys operates under its own municipal government that is independent from the county's government. Nonetheless, the three entities "enjoy a large degree of collaboration and work together to grow the region as a leading location for industry and people". Statistics Canada treats St. Marys as part of Perth County when publishing census data, and most Perth County publications do the same, at least in some sections of their documents.
