Interesting - I've looked at the distillery's site before, and there's no mention of that product - in fact their site says "Oak barrels are filled with the "New Make". Each barrel is numbered and stored in the warehouse for maturation. A spirit must age a minimum of 3 years in wood before it can be called a whisky" (http://www.glenoradistillery.com/smw.html)
So, while the Nova Scotia liquor board has the product catalogued under "Whiskey / Canadian (i.e. rye)", as far as I can tell, the distillery itself is not calling it "whiskey", just "silver".
Actually, it's probably "wronger" to classify that under "Canadian / rye" than under "whiskey", since Glenora makes an all-barley single-malt. One thing it does do is give me some reassurance, that liquor boards will be willing to put a whiskey that's legally not marketable as "whiskey" in with the whiskeys rather than relegating it to the wasteland of unclassified NGS + sugar + whatever.
