I was hired as a contractor through an Agency to work for BMO. I get paid similar to part time: CPP, EI and income tax are taken off my paycheck, but I am not considered an employee of BMO, a common practice in the company to save retirement and health benefit costs. However, what I did not know was that the mother agency of my agency had a rule that contractors cannot stay longer than 18 months, so I was told 3 weeks before the 18 months that they were letting me go for this reason. I would have never agreed to this contract if I knew this information! Has my rights been violated?
