The Marilyn Bell I ferry, which connects passengers, vehicles and supplies to Billy Bishop Toronto City Airport, is now the first electric ferry service in Canada to be powered by a zero-emission, lithium-ion power and propulsion system containing no diesel components.

PortsToronto, owners and operators of Billy Bishop Toronto City Airport, celebrated the return to service of the Marilyn Bell I on December 15, following its conversion to 100 per cent electric power. In operation since 2010, and upgraded to bio-diesel fuel in 2018, the vessel’s diesel generators and engines were removed in 2021 to make way for a new electric power and propulsion system and a suite of lithium-ion batteries fueled by 100 per cent Bullfrog Power renewable electricity.

Powered entirely by electricity from clean wind and solar sources provided by Bullfrog Power, the retrofitted Marilyn Bell I has eliminated greenhouse gas emissions from the ferry operation, reducing the airport’s direct emissions by approximately 530 tonnes per year. In addition to operating more efficiently and eliminating related air emissions, the retrofitted vessel builds on the airport’s award-winning Noise Management Program, as it will operate far more quietly, dramatically reducing related noise in the surrounding community.
