I watched one Doc, that said U-Boats got into the Saint Lawrence.

    The fresh river water, mixing with saltwater, created layers in the river. Rendering sonar ineffective at locating U-Boats. At one
    point, Canada considered closing the river. The U-Boats also deployed a secret weapon to block sonar. It was basically a
    giant Alka Seltzer table. Anyone know more about this?

    I guess Canada started the war with only 5 destroyers, capable of anti-sub work. But, the RCN grew quickly and helped with
    convoys a lot later in the war. I think it was ONS-5, that the RCN was a major factor in the defeat of the Wolf-Packs.

    Just google BOLD and ASDIC, and you will find plenty of information on what you are looking for.

    Didn't Canada finish the war with something like the third largest navy in the world (counting numbers of vessels and not tonnage)?

    Indeed they did, although it helped that most of the larger navies were sunk. Most of the ships were Canadian-built, minesweepers and escorts as you say, but producing over 300 of them in a few years in a country that had not previously built warships was very impressive. They also contributed ships to the RN and a few to the USN.

    Indeed. I should have said number of warships. At various times the US Army has had more vessels than the USN although I don't think they have ever had more combatants except for possibly during the ACW.
