Then it shouldn't be completely difficult, though you have your work cut-out for you. Canada is always looking for skilled tradespersons to fill their ever-growing labour demands. Just keep up the effort and try looking for jobs in those fields.
Try looking at these:

And do as much research you can on the Province you'd like to reside in. Best Wishes.
