The above is for immediate family members of temporary residents in Canada. However , I am permanent resident and I have provided all the necessary documents that my spouse travel is not optional. Still, they have rejected it. Not sure if they have even read through my letters with all the proofs attached.The reason a lot of you are getting denied under the exemption is you have not proved the travel is not optional/discretionary. It’s important that there are letters from both spouses to indicate why the travel is not optional- there has to be some compelling reason. It’s clearly stated here.
“Immediate family members of temporary residents in Canada will still be required to provide evidence that their travel is non-optional or non-discretionary. For these immediate family members seeking to travel to Canada from any country other than the United States, an authorization letterissued by IRCC is required. This letter, issued for the purposes of reuniting immediate family members, should be sufficient evidence that travel is non-discretionary, as letters are only issued by IRCC when travel is for a non-discretionary purpose...”
