Hi all,
For some family reasons, my spouse doesn't want to land with us. I am the principal applicant. What would the effect of this issue? Is it going to affect us? What if the medicals expire and he doesn't land? Please share your opinions and experiences.
Thanks,
if she cannot accompany her with you for landing she can stay at home till when she is able to travel to Canada. As you mentioned the date of medical is very important as she should land in Canada before completing
one year from the date of her medical examination. Better her ticket should be booked at least before one week of that one year completion date. Landing in Canada and return to home country
immediately 
, and then again travel will be tiring and also expensive.
Please ensure that her
original COPR should be left with her and you should not carry it if she is going to travel on a later date.
