You are very welcome. Only the border service officer will determine whether you can or cannot enter Canada. Since you said that your presence is required in Canada, then I don't think it will be a problem. You need to make sure to bring sufficient evidence to show that your entry to Canada is non-discretionary. If you click into the Study\Work section on the website I included in the previous post, you can find specific information there. Also, they require you to have a 14-day quarantine plan. Best of luck.
