In the US, streaming devices are pretty inexpensive. It may actually be cheaper to ship them and pay taxes than the prices I'm seeing on amazon.ca
Sony 7.2 AVR + Sony Stereo Receiver + 2x Phorus PR5 (attach to AVR and Stereo with RCA jacks). That makes a Play-Fi system instead of Heos or MusicCast.
You could replace the stereo receiver with an amp if the right one is available. In the US I'd look at the Dayton Audio APA102BT, or something like it without bluetooth.
Russound, Outdoor Speaker Depot and others have amps that use a similar design with 2 sets of speaker terminals. It also has auto on/off, so it would power on when music plays, then time out after stopping.
I just don't know where else to look in Canada.
Dayton/PartsExpress has an alternative ecosystem. Then you could have a Hi-Fly/LinkPlay system.
A Dayton Audio WBA31 is $42 USD. Treat the same way as a PR5. It also has ethernet (PR5 is wifi only), SPDIF out and can play from and SD card.
A Dayton Audio WB40A is the same thing, but with a 20W/ch amp built in for $98 USD if you don't need it loud (or use sensitive speakers).
It might be worth finding out how much international shipping + taxes are for these devices. The PR5 is a lot more on amazon.ca compared to the US.
Once set up as an ecosystem, you don't need to physically connect the 2 amps together, as long as you use the streaming services they provide.

AVR + stereo receiver with a/b speaker selection for the other zones, and attach streaming devices.
Denon Receiver + stereo receiver + an echo dot/Google home? What connections would I need to have in a stereo receiver?
Connecting one AVR to the other. Would it just be a simple line in connection from AVR1 to AVR2. And could I then control all the zones with an app?
