1. Yes i will be travelling Delhi -> Doha -> Montreal
2.
@sheikhzaid I asked Qatar airways the same question when I was going to India (apparently all passengers coming from Middle East are also required to do RT PCR test on arrival to India as well) Qatar representatives/helpdesks on the airport knew about this and they told me in Montreal as well as in Doha that no you wont need to do another test since the transit period is too short and you are not leaving the chekin area of the airport. The decision to board the flight is taken by the airlines and not IRCC or the arrival country . I am just arranging for a written proof of the same (in email)
