LMIA asshole boss

Hey gang.

I’m currently living in Canada on a LMIA. I am a plumber and have been working for my company for the past 3 years. Sadly my boss seems to of switched up since growth in the company and has been shorting my checks and not paying me reimbursements that are owed. Along side other things.

I have an offer from another company but my concern is about the process of moving company’s and the legality’s of my closed work permit.

Any advice would be great

Thanks ! Xxxx
