Mexico route is the safest and there is no risk involved, thousands of people has already travelled through this route safely.and i am also considering this route when i will have my copr and passport in hands. The people are traveling because there is no guarantee that canada will lift direct flight ban on india on 21st august, it is better to find an alternative to those direct routes and fly to canada because you never know what will be the situation in these covid times.
Moreover, when direct flights will resume then you have to book expensive flights again because the prices of direct flights won't be getting lowered soon according to me as lots of people are waiting for direct flights to reopen.
Let me know what risks you are thinking of in mexico route?
Nothing on the top of my mind. What you're saying makes complete sense to me now.
