Don’t think any government is going to make it easier for people to leave India when the rates of covid are so high. Nobody wants to import cases into their country, risk exposing whole planes including crew and a negative PCR test doesn’t mean you’re not going import Covid. It’s not up to any government to make it easier for people living in India to travel. Even if they set up PCR labs you may have to quarantine in the country for 10-14 days according to current rules unless the labs were in the transit areas. Unfortunately I don’t think travel will return to normal until the situation in India changes drastically.I know that even private planes are not allowed and that is my point that they might give exemptions after thirty days which suits Canada citizens. Also if they are allowing entry to Indians from airports outside India then they could have setup a lab at airports or atleast nearby airports and do a pcr test there and give results in 4 to 6 hours. Last year this was process at Delhi airport where pcr tests were conducted and results were given in 6 hours after which only a passenger was allowed to go.
I am very optimistic that they will come up with better screening process and things will get normal.
