Swamper job

I am considering to move to Grande Prairie from Nova Scotia sometime next year. I was working in the health care for almost a decade on the East Coast and want to change the career into oil and gas. How hard it would be for me to get a swamper job without experience? I used to work as a train conductor back in my home country before immigrating to Canada but it was 10+ years ago. I have a class 5 drivers license..I can do the air brake endorsement if needed + basic tickets.

My ideal plan is to get a swamper job for a HydroVac or similar…stay for 1-2 years there..get my class 3 and become an operator.

Thoughts?
