Canadians know the deliciousness of a Cadbury Caramilk chocolate bar. The liquid gold caramel flowing out of the smooth chocolate pockets, all wrapped up in gold foil, it is one of the most classic chocolate bars I can think of.

What makes it even better, is that they are made in only one factory. First produced at the Cadbury factory in Montreal in 1968, production moved to the Gladstone factory in Toronto in 1978 and have been made there ever since. This sweet (literally) factory makes 700,000 of these delicious bars every single day. It's a good thing they make so many, because Canadians alone unwrap 33 million Caramilk bars a year. 

The secret of how they get the caramel into the Caramilk bars, though, is said to be locked in a vault in Toronto and is carefully guarded and protected.
