Permits & Approvals

Most commercial rooftop and ground-mount solar installations require a building permit from the City and electrical permitting/inspection by the Electrical Safety Authority. Utility interconnection or customer-generator agreements are handled by the local distributor. Always confirm permit triggers with the City of Mississauga and with the Electrical Safety Authority before procurement and installation.

  • Consult Planning Services for zoning compliance and site plan triggers.
