I tried once to withdraw my protected person status due to my mental illness (depression) and since I'm alone here in Canada without any sort of a support
I took my notice of seizure to the cbsa office at airport road, they referred me to their office in Victoria Street downtown
So i did go there, explained the whole situation, they strictly refused and informed me that i had to go through new hearing by IRB member, now that I'm on medication i became able to cope with the new live and doing my best to be strong.
I hope my reply was helpful.
