Thank you very much! I did manage to reach someone at the very last minute, but I will try this next time I need to reach them since I am indeed within Canada.
From what I was told on the phone, I am indeed past both the limit for re-applying or contesting. However, she said that I should try to contest it with proof given that it was denied for reasons that were not actually accurate or valid. From there though, it will be up to them to decide if they do want to take the request for a reconsideration, which is entirely fair given that I am outside the time limit. I am waiting for all the justifying documents to arrive to send it to the IRCC right away. After hearing their decision, I will probably then decide what to do.
Thank you all so very much for your advice on such a messy situation. I sound like a broken record, but I truly appreciate it.
