George W asked:
My bike chain rusted over and I need to get a new one. Does anyone in the GTA know where I could get a new chain and a chain tool to replace the chain?
Or, any places nearby where I could have a professional do it? Preferably the first option, though,
Thanks!

any bike store or some big places like wall mart
Umm even Canadian Tire sells bicycle chains.
