You seem to view me as the fount of knowledge, Dave..
Anyway, Ottawa is difficult, or it is until you are resident here. Once you get that you can move anywhere although the PNP people don't like to see it.
The Prairie Provinces are the ones which offer most opportunities, although there are still some in the Maritimes that are hiring. The thing with the East is that you limit yourself a lot more on where you will be driving.
Best advice at this stage is simple. Make sure you are all aware of each others thoughts on the idea. Don't go off half cocked about it, and be sure you are all in agreement. If you decide to move then put your entire selves into the move, 100%, or there will always be cracks in your armour, and you will need to be together.
