    ⭐ 1/5 As a truck driver, I’ve eaten at more than 20 McDonald’s locations across the GTA. I normally don’t visit the ones inside Walmart, but I happened to be shopping here and decided to grab a quick meal. Unfortunately, this was easily the worst McDonald’s experience I’ve had. My poutine came with no fork, and there were no napkins or straws provided or available at the drink station, so I had to keep going back to the counter to ask for them. The burger quality was also noticeably worse than any other McDonald’s I’ve tried in the GTA. Very disappointing, especially for such basic service.

    Make sure to check your bags before leaving! We ordered cookies with our meal today, paid for them, and drove all the way home only to find out they were completely left out of the bag. Super annoying. Double-check your order at the window because they are clearly rushing and missing items.

    The service at this location relies heavily on gaming the metrics rather than actual efficiency. The team consistently practices premature bumping, clearing orders from the Kitchen Display System (KDS) long before the food is actually bagged.This results in the customer-facing lobby screen displaying my order as "Now Serving" while I am left standing at the counter waiting for several minutes. Serving off early like this might look great on corporate efficiency reports, but it causes massive confusion and frustration in the lobby.Please stop cheating the screen to manipulate your service timers and focus on actually getting the food into the hands of your waiting guests.

    I asked for no cheese. She comes back 5 minutes later and had removed the cheese but forgot a part of it. What a shame!!
