Hi. I'm living in Canada on an open work permt and I wanted my wife to join me to help me during this busy time of the year in my job which has put a lot of physical/mental burden on me. Her TRV was approved recently (we cited same reasons) but when we applied for a 'written letter of authorization' the IRCC resfused it saying her travel is not non-discretionary meaning her travel is optional. She is fully vaccinated with Astra Zeneca vaccine. Is there any way around she can come to Canada?
