It seems you have been issued a Procedural Fairness Letter for being untruthful and/or for providing false information or documents.Same sad story with me, the website is very unfriendly ,i took 2 weeks for me to understand and apply an online application,with the help of friends. They dont provide information through email , calls .just because my transit is through canada for 2 hours , i am crying because they refused me on ground that i lied . I have no idea how thats possible. I decided to change my route , because if people sitting over there arent professional and see our application sensibly, than i have to cry, its so unconvenient.they asked me to reply but i really dont know how to apply again.First of all there is no option, in visitor visa we need to write transit. I know if outsider enters a country they need to be strict and carefull but above someone rightly said, their is serious error in processing process, and people dont read it well to verify well. Its waste of my money on my ticket, leave from job to travel to the city to obtain visa.
Unfortunately, a PFL indicates that IRCC is preparing to ban you for 5 years for misrepresentation
