Thanks a lot for your advice. I'll get a lawyer involved as you had advised. However, I cannot go back to Nigeria or South Africa at this time as I claimed my life was in danger in both countries when I lived there(both countries) + both countries are even under travel ban and all evidences are requested to be submitted before the middle of next month...Well you know Canada always do things their way, and because over the years Nigeria has been going down gradually so any documents that comes from the country is also not wealthy of Canadian standard. The best you can do is get a lawyer involve and it may result in you going to SA or back to Nigeria to do the official marriage with much more evidence to prove. Good luck.
