If you want to really get the MNR rangers excited about whisky, get the Wisers De Luxe at the Canadian liquor store.  It is fantastic stuff, and I'm sure they like it.  You might also try Lambs dark rum, available at the Canadian duty free stores and the government liquor stores as well.  None of that American stuff, eh?  And be sure to call it "rye" instead of whisky.  Unless you have an obvious American accent, they might mistake you as a Canadian.
