I was sponsored by my ex-wife (a Canadian national) in 2015, and I received my PR in March 2015. I lived in Canada from March 2015 to September 2016. We separated in September 2016 for various reasons and divorced in October 2016. (divorced granted outside Canada). It's been more than five years, and I've already remarried, and I'm planning to relocate back to Canada and apply for a landing paper; my question is, can I sponsor my second wife to Canada side by side? or do I need to obtain a divorce certificate from the first wife in Canada first?
