If you want to get rid of them in one go (as opposed to sitting on online auctions sites, which could take a while) you don't necessarily have to come all the way to Toronto. I see you are in Leamington. There's a stamp show coming up in Sarnia on October 5. Most of the dealers do the rounds and hit most of the shows.
That would give you a month to do some research and figure out a price.
You can get current stamp catalogues a most public libraries.
An after thought, there's also John Sheffield's stamp auction house in London. Either way they're not as far as Toronto.
