Even if you find a 'sponsor' , they still need to apply for a Labour Market Opinion from HRSDC (Google) in order for you to apply for a work permit.
I am led to believe that LMOs are not currently available for Air Pilots because
a. There are too few jobs
b. There are too many Canadian pilots out of work
If your 'sponsor' can prove that they can't get suitably qualified pilots than you do stand a chance. This is unlikely in the current situation.
Best of luck
