Air Transat from Pearson - Manchester, flights from around CAN$330 one-way incl. tax etc.
Manchester - Belfast with Easyjet. Fares from CAN$50 one way incl. tax etc. There will be a charge for hold luggage with EasyJet.
Both flights can be booked on-line in advance, from any country.
Others, I'm sure - will advise you on the bus routes and times. I've no idea.

Note there are TWO Belfast airports: Belfast International (sometimes old name Aldergrove is used) code BFS; (George Best) Belfast City BHD.
Good point from *3.
Belfast International is literally miles away from Belfast, right out in the country - whereas Gearge Best is very close to the city centre and docks.

I got cheapest flights Dublin-Amsterdam-Toronto with KLM earlier in the year,on a Tuesday. I just got the bus direct from Belfast to Dublin airport and return. Unfortunately, flights to and from Toronto seem to be hideously expensive at the minute, especially from Toronto, so if you do find cheap(ish) flights do post where you found them (pretty please) so I can fly my sis home for Christmas!!!
