Sell or Drink?

Drink them...that's what whisky is for :-)

Also, not sure there's much of a market for old Canadian whisky.

Expect a probable comment/info, and possible interest from @paddockjudge. Michigan to Ontario is a difficult conveyance, though.

If you're a whisk(e)y drinker I say open them with some friends. If properly sealed (original seal) then they should be perfectly fine to drink. If you don't want to drink them I think you could find a buyer but don't expect collector's prices for them - you'd sell them at drinking prices because that's most likely what the buyer would do with them.

Drink, baby.
