Hi Anto,
I'm from Montreal and moved over here so what do you need to know?
Quebec is a Province, and quite large, have you been offered a position in Quebec City then?
If yes, it's about two hours east of Montreal and slightly more french than Montreal.
It's a very big on tourism so you will find that most people speak english as well as French in the busy parts of the city. Also the french spoken in Quebec is slightly different than the French spoken in France, slight variations of words but the basics are pretty much the same.
Montreal is a much easier city to get to than Quebec City. Unfortunatly there are no direct flights from Dublin to either Montreal or Quebec City. If you're going between June and october your best bet is to fly Air Canada via Toronto where you should get a flight to Quebec City. Otherwise you will have to fly via Heathrow or Paris. Heathrow can be unreliable at best (
see this link) and I doubt you'll get a flight to Quebec City from there, Paris might be a better bet, otherwise you could always fly to Montreal and make your way to Quebec City.
I guess the question is what do you need to know to make your decision? It does get cold in the winter, most of the time around minus 28, there are a few weeks in February that can get as cold as minus 38 or so but you dress for it and spend little time outdoors. Boots, coat, hat, scarf and gloves are required! If you've ever wanted to ski there are loads of great ski hills nearby and a visit to Montreal is a must.
Quebec City has a lot of history to it and has loads to see and do when you're there. In the winter, and I guess I'm presuming that you'll be there in the winter, there is a famous winter carnival with an ice hotel and bar and everything so if you are going there you won't have to look far for things to to.
