    11 21 on Tuesday February 24th and the place is closed. Clearly says open till 1 am on the hours. Ive stopped here past 11 before. Specifically drove to newmarket for Mr sub as hours say "open." Extremely disappointing. Mr Sub use to pride themselves on canadian customer service.

    Ordered cold cut on white, double meat double cheese and bacon. Only regret was not ordering double bacon. Delicious sandwich, a must try.

    I went there today specificity for the Louisiana Chicken Wrap ... For some reason I'm not able to order this on my app. Large wrap extra chicken and extra cheese.....I spent over 20 dollars on this pathetic excuse for a meal. Ive never been disappointed at Mr.Sub. ever in my life. Instead of a huge round wrap I'm used to getting when I ordered this. It was flat and had more tortilla than chicken. Not even enough chicken to fill a small tortilla wrap. Location was at Mulock and Young in Newmarket. Do better !!!!
