The neighbourhood

Sprigings works out of a low rise commercial building on Norseman Street in Toronto's west end, in the Etobicoke stretch of light industrial and office buildings off Islington Avenue rather than the downtown core where many Toronto litigation firms keep their offices. That location fits a practice built around out of town pharmaceutical, biotech, and consumer goods clients more than local walk in traffic: the firm's own contact page points people to Islington subway station for a short bus ride in, or to the Gardiner Expressway for driving in from elsewhere in the GTA. The firm also notes it operates within Treaty 13 territory, land traditionally used by the Mississaugas of the Credit First Nation, the Anishinaabeg, the Chippewa, the Haudenosaunee, and the Wendat peoples.
