[2] By 1930 the Battle-class trawlers which had been re-designated as minesweepers in November 1922[3] were coming to the end of their effective service lives.

[4] In the naval estimates of the 1936 budget, provision was made to replace two of the Battle class with two new, modern minesweepers.

[7] At the outbreak of the Second World War, the Royal Canadian Navy considered constructing more, but chose to build Bangor-class minesweepers instead upon learning of that design.

[12] The Fundy class was propelled by one shaft driven by a vertical triple expansion engine powered by steam from a one-cylinder boiler.

They continued this way even after the outbreak of the Second World War, until March 1940 when Comox and Nootka were transferred to the East Coast.

[12] On 1 April 1943, Nootka was renamed Nanoose in order to release her original name to a newly constructed destroyer.

[14] In January 1945, Fundy and Comox rescued survivors from the merchant vessel Martin Van Buren which had been torpedoed.
