The Stockyards definitely has one of the best burgers in Toronto.
I had a classic with bacon and cheese, plus fries and a bottled soft drink. The total was $17. Yes, you're gonna pay more than most places, but it's worth it if it's once in a blue moon.
The patty was juicy and fresh, the bacon was the best I've ever eaten on a burger, and it was topped with red onion and tomatoes. The shoestring fries were top notch.
The only con was the seat near the front door - a bit chilly at this time of year with so many customers coming and going, letting the cool air inside.
I went in the middle of the afternoon, thinking it would be a bit slower. I was surprised because it was very busy. I managed to snag a seat right away, but others behind me had to wait for others to finish and GTFO.
