Active Surplus type shops in eastern ontario?

I grew up in toronto when active surplus was still kickin' and you could browse for hours, just soaking it all in and getting inspired.

I have a few projects in mind. Mostly things I want to do with electromechanical controls for around the house and I'd love to find a place in eastern ontario that is similar. I know for mechanical components some of the flea markets are a good place to go, but what about electronics? Does such a magical place exist???

I know about pi shop which has some of the things I am looking for but I'd love a brick and mortar junk shop to wander.

Posting in Ottawa because it seems like the best bet, but I'm not specifically looking for Ottawa. Anywhere 613 would be great.
