Passport expiry date for entering Canada on TRV

[tjkdl]

Hi,
My mother in law's passport is expiring on Aug 4, 2024, her Canada TRV is expiring on Aug 3, 2024.
Can she enter Canada in January 2024, which is more than 6 months before the expiry date?
There was one saying about the 6 month requirement is for the date you plan to leave Canada, but not the date you enter Canada. Can anyone please clarify?

Thanks!
