There were 4400 people living there at the time, mostly in St Pierre. My wife has relatives there, and brought back some marvellous cognac, duty free. I've only seen it from both sides, but didn't take the ferry from Fortune. The concept of shipping in Canadians to live there, Soviet or Nazi-style, is fairly ludicrous because they should want to be there, and they would have to have something to do when they got there. It's biggest value is as a fishing port, and a way to impose fishing rights. Canada wasn't, and had no reason to be, interested in annexing the islands, except as a Fresian-style staging point to invade the Burin peninsula and eventually take The Rock, bye.
