Mayfield West (sometimes called Southfields) is a suburban neighbourhood located within the largely rural Town of Caledon, in Peel Region in Ontario, Canada, immediately adjacent to the City of Brampton.

Near Highway 10, it surrounds the Brampton neighbourhood of Snelgrove, a former hamlet which extends slightly north of Mayfield, on three sides.

[4] Kennedy Road runs north-south through its centre, and is partly lined with storefronts as a new urbanism node within it.

Small-scale development was happening in Caledon at the time, mostly near established communities, chiefly due to its close proximity to Brampton.

[11] Mayfield Road runs east-west along its southern boundary with the City of Brampton.
