It's ok, based on the video of the show, the lumberjack show is a lawsuit waiting to happen. One person with an allergy of those trees gets sick on a visit, that show is done (kinda what Disney might be hoping for anyway). There are allergies to sawdust and different types of pollens from trees and such. Why Disney would go this route with a show is beyond me.
Before anyone comes on and says, "well, they don't have to watch the show", you're right, they don't... And the person that gets sick (to a possibly unknown level) may not be attending the show. They may be just passing through Canada on their way to the UK or another country in the World Showcase.
Also, from the video shown, this thing looks like the stupidest, hokiest thing ever. Certainly not worth getting rid of a band like Off Kilter. But hey, I don't get paid the big bucks to cost the company lots of big bucks.
