I am currently on LTD since March 2022 and I received a letter from my insurer stating that my employer has stopped paying for my benefits as of December 31/2023 but have not heard from the employer about this.
Are they able to do this?

Unfortunately, there's no easy answer to this question. It may not be allowed, but it depends on a few different factors, including your employment contract. If you are non-unionized, I recommend giving our employment team a call at 1-855-821-5900 and schedule a consultation to discuss this matter in more detail. If you are unionized, you will need to speak with your union representatives.
