Emirates Airlines - Cancelled my booking

I was issued a ticket # *** ********** from Mumbai to Ottawa. My Dubai-Toronto flight arrives in Toronto at **:**. And my next flight is at **:** from Toronto to Ottawa. In spite of having enough connection time of an hour and ** mins, my flight is cancelled by Emirates telling me the reason of less connection time, which is so wrong. The airlines has screwed my booking giving me next flight departing Toronto at **:**. Due to my health reasons, this is too late for me and not safe at all. Attached is the original ticket which Emirates is refusing to issue me.
