In Canada during World War II, Baldwin worked on an experimental [[smoke screen|smoke laying]] hydrofoil (later called the Comox Torpedo) that was later superseded by other smoke-laying technology and an experimental target-towing hydrofoil. The forward two foil assemblies of what is believed to be the latter hydrofoil were salvaged in the mid-1960s from a derelict hulk in Baddeck, Nova Scotia by Colin MacGregor Stevens. These were donated to the Maritime Museum in Halifax, Nova Scotia.

The [[Canadian Forces Maritime Command|Canadian Armed Forces]] built and tested a number of hydrofoils (e.g., Baddeck and two vessels named ''Bras d'Or''), which culminated in the high-speed anti-submarine hydrofoil [[HMCS Bras d'Or (FHE 400)|HMCS ''Bras d'Or'']] in the late 1960s. However, the program was cancelled in the early 1970s due to a shift away from [[anti-submarine warfare]] by the Canadian military.  The ''Bras d'Or'' was a surface-piercing type that performed well during her trials, reaching a maximum speed of {{convert|63|kn|km/h}}.
