Another vote for Claire in Montreal, John. She carries eveything under the sun and has really resonable shipping fees along with very fast delivery. You won't be disapointed.
Perhaps not as useful to those on the west coast, however:
I recently had some dealings with Nymoc chemicals in Toronto (416 465 1929), and they were fantastic. Everything is packaged and labelled properly, and they seem to stock all things photographic. They even stock high quality brown glass bottles at good prices.
I once bought a big (25kg) bag of sodium sulfite (anh) from Signal Inc. (416-461-7196) in the east end of Toronto. I'm not sure of the current pricing, but it was dirt cheap. They only sell bulk, and I'm not sure if they will ship. Still, it's a handy source. Only problem is storing the stuff!
I dealt with JD photochem years ago, before Claire took over, and to be honest I wasn't thrilled. Hopefully things have changed with the new ownership.
One of the fellows in the darkroom gave me the idea of using one of the small pocket scales sold primarily for weighing marijuana. It was readily available at The Friendly Stranger (a paraphanalia shop on Queen St.), and seems to do the trick fine. 0.1g -> 300g, for $40. Not bad, really.

I'll third the recommendation for Claire. E-mail her, though, for her most recent price list -- the ones on the website are usually out of date. Nymoc sells a lot of what she carries, but I've found their prices to be much higher (though the convenience factor is there if you live in Toronto and can get to Queen and Broadview before 6 pm).
