Hey, sorry for bothering you, just one more thing. I have already applied for an exemption. Will they deny it by any chance? It was not my fault I could not travel earlier. The visa offices were closed before my passport could be stamped.You can be denied boarding a plane to Canada with an expired travel letter. It doesn't matter to CBSA that you left your country on the 16th and had to quarantine. Again you will not know until you try to board.
