HMCS Victoriaville was a River-class frigate that served with the Royal Canadian Navy during the Second World War.

[3] The River-class frigate was designed by William Reed of Smith's Dock Company of South Bank-on-Tees.

[5] The name "frigate" was suggested by Vice-Admiral Percy Nelles of the Royal Canadian Navy and was adopted later that year.

[5] 15 Canadian frigates were initially fitted with a single 4-inch gun forward but with the exception of HMCS Valleyfield, they were all eventually upgraded to the double mount.

[6] For underwater targets, the River-class frigate was equipped with a Hedgehog anti-submarine mortar and depth charge rails aft and four side-mounted throwers.

[5] River-class frigates were the first Royal Canadian Navy warships to carry the 147B Sword horizontal fan echo sonar transmitter in addition to the irregular ASDIC.

[3] Later in May 1945, Victoriaville traveled to Saint John to undergo a tropicalization refit for possible service in the southern Pacific Ocean.

However, with the increasing Soviet submarine threat, the Royal Canadian Navy sought to augment its anti-submarine forces.

[3][10] On the night of 4 October 1967 there was reported an impact of an unknown large object into waters near Shag Harbour, located in Barrington on Nova Scotia's South Shore.
