The neighbourhood

Gagan Law's office is on Water Street in Streetsville, land first opened for settlement in 1819 and incorporated as its own village in 1858, before it amalgamated into Mississauga in 1974. Streetsville kept its own street names after joining the city: the roads that became Mississauga Road and Bristol Road elsewhere still run through the village as Queen Street and Main Street, past many of the area's older buildings.

The city treats Streetsville as a Community Node, a designation for an area with its own local shops, restaurants, schools, and services rather than a stretch of highway retail. That kind of small commercial core suits a firm whose real estate and business work runs mostly to homes, small companies, and family estates, and Gagan Law also serves clients from Brampton and other communities across Peel.
