Return tickets for visitor visa

[Bernadettee]

Hi,
My parents got their trv approved for multiple entry on June 8. Should they have to book their return tickets. I read many threads saying their approved stay in Canada depends on the officer at the port of entry. I don't have any idea about this. Please advice me.

If they have a regular TRV rather than a super visa - they must book return tickets. The airline most likely won't let them board the plane to Canada without them.

They have TRV.
Can the return tickets be dated for a span of 6 months? Say for example, if they come to Canada on June 20, can the return tickets be dated on December 5?
