If you're craving a hamburger in Toronto at 6:30 a.m., you won't be able to grab one at Queen and Spadina. That's because the 24-hour Hero Certified Burgers at the intersection's southeast corner closed down over the weekend.

"After 21 years, the era of Lettieri Espresso Bar and Cafe and Hero Certified Burgers comes to an end in this landmark location. Our lease term at the corner of Queen and Spadina has expired," reads a note, signed by Hero Burgers' Founder John F. Lettieri, posted to the fast food joint's front door.

But don't worry, you can still satisfy your late-night burger cravings in this high-traffic area thanks to the McDonald's kitty-corner from the now-shuttered Hero Burger.

It'll be interesting to watch what moves into the first floor of this heritage building next.

What should replace this 24-hour Hero Burger at Queen and Spadina? Let us know in the comments.
