Looking for a dishwasher, and well water systems shop

Hey all, other than Canadian Tire, are there any really good appliance stores around that are local who can help with picking out a dishwasher as well as the install. We don't have any kind of hookup so we'd have to do some shenanigans to make it work but it would be awesome.

Also, we are on well and septic. Our water system is very old as we took it over when we bought our house. It's easily 20+ years old. We are looking for a whole new system... something with instructions. The guy we bought it from told us nothing and we are new to all of this. I get what I am doing now but damn, what an adjustment.

Doesn't have to be in Ottawa but ideally Ottawa or areas east of it like Rockland, Limoge, Embrun etc.

Any help would be great!
