That sounds about right.
I agree. Was there anything significant going on anywhere in Toronto near there (a big game or big event of some sort)? I doubt that this guy was interested in taking out a donut shop.
Incidentally, I think there is no possibility that he was a suicide. I have a relative who committed suicide in a rather spectacular manner, and I read a lot about it afterwards. People who do things like strap themselves to a log going through a sawmill, set fire to themselves, or blow themselves up want to be seen. This is called suicide "on the head of" someone else - that is, the suicide wants everybody else to feel guilty for all the (real or imagined) wrongs done to him. So this is not the type of suicide for a men's room where nobody will see - just as the OU bomber was not committing suicide on a bench behind behind some empty buses. These were "work accidents."
