I've never heard of it in Nova Scotia however never say never. We had 2 moose (that we know of) just a couple miles down the road that had a bad problem, they would just walk around in circles in a farmers pasture and eventually died. DNR were called however never showed which is typical around here. After reading your post I did a quick google search and came up with this as well as others.
