HMCS Comox was a Bay-class minesweeper built for the Royal Canadian Navy during the Cold War.

The Bay class were designed and ordered as replacements for the Second World War-era minesweepers that the Royal Canadian Navy operated at the time.

Similar to the Ton-class minesweeper, they were constructed of wood planking and aluminum framing.

[note 1][3] The Bay-class minesweepers were powered by two GM 12-cylinder diesel engines driving two shafts creating 2,400 brake horsepower (1,800 kW).

[4][5] The vessel was commissioned into the Royal Canadian Navy on 2 April 1954 with the hull identification number 146.
