Family of work permit holder entering Canada without the work permit holder..

[vness]

Can anyone please advise...

For the family of a work permit holder from a country that requires a visa...

Work permit was approved and passport request letter was received for the applicant - then two weeks later, passport request letter for the spouse and request for medicals for children..

How does it work if the family travels at a later date then the work permit holder? Will they still be processed as family of a work permit holder and be granted entry for an extended period of time?

Thanks to anyone that has the answer!!
