The world, with some restrictions. Canada has sold technology to countries that have used it to our disadvantage, the best examples are nuclear power which has been used to make nuclear weapons.

Plutonium is always produced by using uranium fuel in a nuclear reactor, but it stays in the spent fuel unless this is processed. I don't think Canada has any processing capability for separating out the plutonium, but you need to ask the question to the Canadian authority
In the US nuclear is about 20 percent of generation, and in Canada I believe it is about 15 percent. Different countries have their own energy solutions depending on circumstances. Canada has a lot of hydro possibility which is ideal given the right situation, as it causes no pollution and is renewable. France for instance decided to go largely nuclear, as their hydro was limited and largely already exploited, and they had no oil or natural gas, and limited coal, as a result they have about 75 percent nuclear. On the other hand Australia has plenty of coal and no neighbours to complain about acid rain, so they have not used nuclear at all. Also they must have decided not to create a nuclear industry for the sake of acquiring nuclear weapons, as Pakistan India and Israel have done. So different countries do have reasons for different policies.

Many countries have nuclear weapons today including the United States. China, North Korea, South Korea, and Japan also have nuclear weapons.

the first five countries that were involved in nuclear weapons are as follows;United StatesGermanyGreat BritainRussiaArgentina
I believe the answer you are looking for is Japan - they had a secret nuclear weapons project which was exposed.
None. No nuclear weapons were used in Viet Nam.
As the category for this question is "Nuclear weapons", I'm presuming it refers to nuclear arms.As of 2012, the three countries with the largest stockpiles of nuclear weapons are, in order from most to least:RussiaUnited StatesFrance
Proliferation of nuclear weapons refers to the spread of nuclear weapons amongst different countries. First the U.S. had a nuclear bomb; then the Soviet Union had a nuclear bomb, followed by other countries such as the United Kingdom, France, China, India, and so on.
