But after weeks of it being found to be missing, they are only now calling in the RCMP, and after the NDP raised concerns.
Given the high value of the missing metals, NDP MP Thomas Mulcair said yesterday that mint staff should be calling on police to immediately launch a criminal investigation.
"There's no possible way to explain the loss of tens of millions of dollars through simple administrative or bureaucratic foul-ups and missteps," he said in an interview.
"People understand that mistakes happen ... but they tried to dismiss the whole thing from the beginning," said Mulcair (Outremont). "Well, if there's tens of millions of dollars missing, there's clearly lots to worry about... This is a really serious amount of money and it deserves really serious attention."
