What your listing says and what the coin says are two different things. The coins says that it is 1 oz argent *silver* pur (Pure). What makes you think this is not a true "Silver Maple" similar to the US Silver Eagle? I have added a link to the Canada mint that shows the same coin for 2014 as real Silver. If I had more credit I would be bidding but I think you are selling the items short best of luck.
It does more than one year i bought a lot of coins including this one and who sold it to me said that this was silver plated but i never did any test and i put it in auction listia and not for money. that’s all what i can say. thank you
