I do not know this outfitter but based on some recent problems with a caribou outfitter in Quecbec reported on another site and the recent news out of Labador (see the article on this site), I would make sure I thoroughly research the outfitter and make sure the contract is well written and clear about what happens if the season is cancelled. In one case the outfitter went bankrupt and there is not much that you can do to protect yourself from that, but in another case the outfitter just cancelled the season because they were not seeing caribou.
