In accordance with the Toronto Port Authority's Operating Regulations, anyone wishing to carry out any diving activities within the jurisdiction of the Port of Toronto, including recreational or commercial diving, must first obtain authorization from the Toronto Port Authority through the submission of an Application for Authorization of Underwater Diving form. As such, commercial divers, as part of the application, are to provide proof of insurance (Commercial General Liability) naming “The Toronto Port Authority and His Majesty in Right of Canada” as additional insured and to complete a Underwater Diving Permission (18 years of age or over) Conditions, Waiver & Indemnity form signed and witnessed on behalf of the company.

Insurance is not required from individual pleasure divers but they are required to sign a Underwater Diving Permission (18 years of age or over) Conditions, Waiver & Indemnity with the Toronto Port Authority, and have that waiver witnessed.

The standard administration fee for diving activities is $20.00 + HST per calendar year (January 1 to December 31) per individual, and $100.00 plus HST per calendar year for commercial diving companies. Please make your cheque payable to the Toronto Port Authority or telephone 416-462-3937 and provide a Visa or MasterCard number.
