Of course they did. The entire "free" world benefited from the industrial mobilization of the US during the War. Trade with Canada improved, and with the post-WWII housing boom we bought many things from Canada including machinery and, most visibly, timber to frame all of the new houses with. This is a very simplistic answer so I suggest that you look further into Canada's history. By the way, during the War Canada supplied the US with war material.
We know who we, and others, are.
Canada, New Zealand, and Australia were no longer part of Britain's Commonwealth after WW2. Canada worked closer with the US, being geographically closer anyway...and the US Army built the Alaskan Highway THROUGH Canada from the lower 48 states up to and through the current state of Alaska. With Japanese Forces OCCUPYING parts of Alaska, it was important to get troops up there. Canada is PART OF NORTH AMERICA too. Canadians consider themselves to be "Americans."
Canada is north of the United States.
The U.S. has never owned Canada.
If you mean who are U.S.'s neighbors they are Canada and Mexico
Canada and Mexico
Canada is a huge country, direct neighbours to eleven US states.
The three languages spoken by the United States' neighbors are Spanish in Mexico, French in Canada, and French and English in Canada.
The three neighbors of the US are Canada, Mexico, and Cuba. In Canada, English and French are the official languages. In Mexico, Spanish is the official language. In Cuba, Spanish is also the official language.
The right to travel with a US passport is one benefit of being a citizen of the US. US citizens need a passport to travel to other countries.
There are several neighbors to the US. There is Canada, Mexico, and Russia, although Russia is across from a small amount of water west of Alaska.
By being gord
Mexico, Canada and Russia (the closest distance from the USA to Russia is 3.8km)
The chances of Canada being invaded by the US are non existent.
One of the benefits are that you get to be protected by the us army
The neighbors and us had a barbeque party together.
