I remember reading a story about how some of the first POW's were offloaded in Halifax and shipped west on the train. They asked where they were and got told Nova Scotia...then at the next meal break....New Brunswick...and ended the day in Quebec. Next day when they asked where they were and got told Ontario they figured they were making good time...until they got told the next morning they were still in Ontario....
And after much discussion back and forth the realization came in that Canada was a really big country if you could travel more than a day in one province and that it would twice as long to capture as France.
Even today it's about 6 hours driving from the Manitoba border to Thunder Bay, Ontario...and another 14-16 hours depending on conditions and OPP on getting to Ottawa Ontario before entering Quebec.
They were lucky they weren't sent Downunder - where many, many, Italians were sent from the North Africa. Here, an American was once claiming how "big Texas is! You can get on a train and still be travelling on it the next and still not left Texas!" The Australian farmer listening just said, "Yeah, we got trains that slow here as well!"
Australia is as big as Canada with less population. It is, once you leave the SE corner, largely arid, with water holes few and far between and rivers even less available. Most Italians realised they were a long, long way from home and were used to work on the farms that were vacated by the men to fight them and their Axis partners. We don't have just dangerous wildlife, we have 8 out of the 10 most venomous snakes, three of the most venomous spiders, venomous octopi and shell fish and big, big, nasty sharks and long, long, kilometres of empty arid landscape to cross to get anywhere. Australia was well chosen as a prison when it was started.
