I have been reading the Canadian currency act and have found no repeal of melting silver. Now, obviously, people and business have done it, but have they had to ship Canadian currency out of the country? As far as I can tell, unless there is specific legislation somewhere relating to the melting of silver coin by a private entity, it would still be illegal as they would qualify as current because they were issued under the authority of the royal Canadian mint act, and therefore considered current coin (I can use a silver quarter at face value to pay a debt.)
7. (1) A coin is current for the amount of its denomination in the currency of Canada if it was issued under the authority of
(a) the Royal Canadian Mint Act; or
(b) the Crown in any province of Canada before it became part of Canada and if the coin was, immediately before October 15, 1952, current and legal tender in Canada.
And the only thing it prevents is melting current coin (note that a defaced Canadian coin is no longer considered current either.)
7. (2) (2) No coin that is bent, mutilated or defaced, or that has been reduced in weight otherwise than by abrasion through ordinary use, shall pass current.
11. (1) No person shall, except in accordance with a licence granted by the Minister, melt down, break up or use otherwise than as currency any coin that is current and legal tender in Canada.
The currency act is found here. http://www.canlii.org/en/ca/laws/stat/rsc-1985-c-c-52/latest/rsc-1985-c-c-52.html
The other couple of thoughts that I have, is that I should be able to melt any US copper coins all day long. They are not now, nor ever have been considered "current" in Canada. I also should be able to melt down any Canadian coins that I run across that are bent, cut, mutilated or defaced as they are no longer considered current coin. In theory, I should be able to import all of the American copper I want and turn it into a commodity (though I feel certain that in practice, this would result in bad things happening to me.)
Any thoughts, disagreements, additions?
