Have no idea, give them a call and ask. When I went to renew my car sticker I asked to get a new fishing license and she said they don't do that. Well it's a Service Ontario office, it should be called Limited Service Ontario. I had to go to CT and now only 2 in all of Scarb sell them.
From what I was told by a store owner, they have to buy the licenses from the MNR, cash upfront, and they don't want to or can't spend for licenses that may not sell. So the store owner's have to anticipate how many they will sell in a season, I don't know if they re-embursed for the extras. When they run out they won't buy anymore till the next year, atleast this one store owner would'nt.
Call Sail up and ask, I think BPS doesn't sell them.
