Normally in a international flight, you'd fly to Toronto first. That takes 30 minutes. Next you fly to Ireland to a large aeroport, (I've only flow to England) and that takes approx. 6.5 hrs. there, but since this is to Ireland it's more like 6.2hours.
So, not too long.

Well, I live in Ottawa, so not very much time at all.
The drive from Toronto to Ottawa is 452 km - about 4 hours 42 mins.
