The Mississauga commercial solar market

Mississauga has the second-largest commercial solar install volume in the GTA after Toronto, driven by its concentration of large flat-roofed logistics and manufacturing buildings along the Highway 401 and Pearson corridor. Alectra Utilities operates one of the fastest permit-review processes in Ontario — commercial net-metering interconnection typically approves in 2-3 weeks. Mississauga's industrial zone around Dixie Road and Mavis Road is a particularly active commercial solar market.
