Passports, Letter of Introduction or any document posted on your CIC account by IRCC.Okay. Thank you. Would you be able to provide the list of docs we need to carry if we are going to drive? Not urgent, when ever you get time. Thanks again.
Marriage Certificate
Employment Letter indicating salary, when does the job start and where etc.
Kids' details if traveling with you - passports, immunization, any school/grade information.
Bank account details
Car Title is a must - do not try to take leased or financed car.
Fill the RIV forms online at least a few days before traveling that show that you are exempt from paying any duties at the border if you are on WP. For this you need to upload title, car photos and import/export exemption form issued by your manufacturer.
Status in US - what were you doing before moving to Canada.
Take your inventory of items with you and following you (if you used a movers) - this isn't important for those with WP. But just tell the officer that you have stuff coming with you and after you. They will explain what to do and how to get your stuff across border.
Driving license or IDs.
I will post if I remember anything.
