The Manitoba Employment Standards Regulations, https://www.canlii.org/en/mb/laws/regu/man-reg-6-2007/latest/man-reg-6-2007.pdf list the ESC exemptions. Section 5 deals with professionals. It says:

Division 10 (termination of employment), Part 2 does not apply to an employee who
(a) is qualified to practise and is practising or employed in a profession that is governed underan Act of the Legislature that applies solely to the profession; or
(b) is registered or enrolled and employed as astudent-in-training in respect of such a profession
Check the other parts of the Regs. for ESC application to other occupations and industries. Hope that helps. Glenn
