Hey Tarandeep,
answers below.
1) Still do my parents need 90 days temporary health coverage insurance? When OHIP will be covering my parents?
Due to COVID the OHIP starts the day they land. I am not sure how it will work as they can only apply for a health card after quarantine along with an address proof (which can take some time). . I am hoping incase required there would be a process for PR people without a health card.

2) Do my parents need a physical plan for quarantine that they have to show to CBSA while landing or they can verbally say that they will be quarantined at my son’s house?
Yes they will have to submit a plan on paper about quarantine - we did mention a that my mom will stay at my house but she will have her own bedroom and washroom. I will provide food in the room.
3) What are the services/documents they are qualified for like SIN, OHIP card etc etc?
They qualify for all these SIN, OHIP applicable to any PR (will have to apply after quarantine) . Only thing they cannot get is financial benefits for 20 years.
4) What are the documents they need to carry along with them to show at Delhi airport and at Pearson airport?
Passport, Copr, proof of relation with you ( copy your PR card and passport may to show relationship) - this was asked multiple times at delhi airport. first officer didnt knew if she can travel so was sent to multiple ppl till it sorted put. So i would suggest a copy of the webpage that says they are travel exempt.
Hope it helps!
