If your student's thesis/research project involves human subjects in anyway, you will need ethics approval from the McGill Faculty of Medicine Review Board. If the project is a sub-project, the project Principal Investigator is required to apply for an addendum even if the original project already has Institutional Review Board (IRB) approval.
More information regarding the process to obtain IRB approval can be found at https://www.mcgill.ca/medresearch/ethics/forms/.
More specific information about all aspects of the thesis can be found at www.mcgill.ca/gps/thesis such as initial submission deadlines, external thesis examiner, thesis formatting, final submission dates, etc.
