Can my court marriage date be different than the religious marriage date?

Hi, My wife and I are both christians and had a religious ceremony in the church in the month of Feb 2020. We where not able to register our marriage as we went into lockdown during our planned/scheduled time to get our religious marriage registered. I am right now in Canada and want to come back to India to get our marriage registered, but we want to perform a court marriage vs the marriage registration as we want the date of the marriage to be during the visit to the India (next month) and not Feb 2020 which is the date of our religious wedding. Is this considered illegal? Reason why we want the date to be different: One of the rule to have a legal PR is during the first landing to Canada I am supposed to declare if I am married, which I did not(As I had not registered) as that would mean I should have stayed back in India for more than a year after my registration being done. Can you please help me with a legal advise regarding my situation and how I can overcome any repercussions.
