From what others have shared, it appears that after you notify them about being outside of Canada and asking permission to do the test from your host location, they will reply and indicate that is ok, I don't know if this has changed, but it appears that the instruction is that when you go through the process of accessing the test you will need to answer "Yes" to the question about being in Canada. As I said this the information I have gathered from others sharing their experiences and don't know if IRCC has been able to change that step at this point.
If there is anyone that has gone through this experience, could you please share if what I described above is still the case?
