hello, my visa expired on the 31/03/2020, i had prepared all my documents to apply for the extension. but due to COVID, one of my papers from my institute was delayed and by the time i had got it, it was way past the 90 days for the restoration. i had stopped studying that fall since i was not allowed to. then i tried to leave the country as stated on the website. but the borders to my country was closed and i couldnt leave till the 31/12/2020 when the borders opened an i left. now i wish to return to Canada to continue studying from Jan of 2022. i would like to know what i should do to restore my permit and visa.
