Working Without a Permit

Laws and regulations require that the City of Toronto ensures safety bylaws are adhered, zoning regulations are maintained, and codes are satisfactory for plumbing and electrical systems. Having a building permit ensures laws and regulations are maintained.

If you begin construction without a permit, you could face serious charges and potentially costly consequences during your construction project. Make sure you adhere to the requirements of the City before you begin construction.
