Stinky magic -- Toronto's Waste Wizard
The City of Toronto has a website to make it easy for people to figure out if all manner of household items are recyclable, and they've given it a catchy name -- the Waste Wizard.
A test run found it pretty good. Here are the answers for the above items.

Pie plate: Please place this item in your Blue Bin. If appropriate, please empty and rinse this item.
Dog poop: Please place this item in your Green Bin. Line either your indoor container or outdoor Green Bin with a plastic bag or kraft paper bag.
