HMCS Smiths Falls was a modified Flower-class corvette that served in the Royal Canadian Navy during the Second World War.

[3][4][5] The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877.

[6] 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.

Eventually the Canadian corvettes would be modified to allow them to perform better on the open seas.

[2] After arriving in late December 1944 at Halifax for deployment, Smiths Falls took until February 1945 to fit out.
