HMCS The Pas was a Flower-class corvette that served with the Royal Canadian Navy during the Second World War.

[4][5][6] The "corvette" designation was created by the French in for classes of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

[7] During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design.

This took place at Liverpool, Nova Scotia beginning 27 November 1942 and lasted two months.

In September 1942 she was placed under United States command as an escort for convoys between New York and Guantanamo.

[12] After working up following her refit, The Pas returned to WLEF and in June 1943 was assigned to escort group W-4.

She was badly damaged in a collision with SS Medina, a merchant ship, in the western Atlantic on 21 July 1943.
