I've been employed by my employer for about a year or two as a part time employee working on the weekends when I first started. In 2021 I switched to full time on payroll as a seasonal employee. In July of 2021 I bought a new truck. I then negotiated a rate with bonuses with my employer during the off season for the following 5 years as a subcontractor, he agreed. There was no contract, it was a verbal agreement. Since then I have worked every year for my employer, excluding the winter months. I am due to start working this upcoming season sometime this month. My employer called me last month and told me that if I decide to return this season that the pay will not be hourly anymore and that it will be changed to a flat rate. He has been trying to convince me a few times last year to do a flat rate of pay, which every time he asked, I declined. I do not want flat rate as I know I will make less. As per our verbal agreement, I still have 2 seasons left to work under that arrangement. Even tho I am a subcontractor in Ontario, is this a constructive dismissal? And would I be entitled to severance?
