Extreme Stomach Pain from Meal - McDonald's, Ottawa Ontario

1007 Saint Laurent Boulevard, Ottawa, K1K 3B1 Ontario, Canada

I went to this place, yesterday May 25 at noon..my stomach pains are extreme no matter what I take to try & get rid of them.
it is the only place where i have not eaten at home since Saturday, May 21 so I am confident it was something at this place
I do not know the east end of Ottawa very well but this metro Canada is on st Laurent just before Donald. I only know this cause the lights at Donald were out causing tremendous backlog of traffic in both directions | Symptoms: Stomach Pain
