Update

Dad's in the Toronto General Hospital, Floor 7B, Room 106, Bed 1. Don't try calling him. He can't be reached by phone at the moment.

So, as a first course of action, the nurses tried inserting a catheter to help dad go to the bathroom. It was very painful for him. And in the end, all that dad was able to pass were small dried blod clots. Something is definitely not right. The doctors will be in soon to run many a test to get to the bottom of the situation.

Keep praying.
