Cost of living is pretty similar to home I think. To get those wages you have to have a Canadian journey man ticket. You will have to register as a fourth year apprentice here, work for a year before you sit the exam to become a journey man. http://www.saskapprenticeship.ca/WOR..._SASKATCHEWAN/
I think it would be a good place for a family,as long as you can adapt to the cold in the Winter.
Have a look at Alliance Energy, I think they may have been trying to recruit Irish people. Other than that you could have a look at saskjobs.ca to see all the companies that are hiring.
The bcca is for British Columbia, Saskatoon is in Saskatchewan. Different provinces have different rules.
