Finding graphic design (publishing) jobs in Toronto and relocating

Hi, we are a family of three. Both of us are newspaper professionals. Our son is 4 yrs old. We are thinking of places to relocate to for a better life and better opportunities (educational and lifestyle) for our child. I'm in the editorial middle level managerial position in a newspaper while my husband heads the design section. Can anyone guide us as to whether it is a good idea to think of Canada as the new destination? And how does one find a job before visiting the country? Help!
