Want to get married in the process of immigration to Canada

It won't have much impact, because your family is an investment immigrant, which is not exactly the same as a skilled immigrant.

It's just that the time will be delayed, and supplementary information and some explanations need to be submitted for review. I suggest you write a fact sheet with sincere wording. Add some stories about you and your lover. If it is true, the immigration officer is probably very reasonable.

Suggestions on the first floor are also optional, but if you get married within a short time after getting a maple leaf card, the authenticity of the marriage will also be investigated.

So which way to take needs to be discussed with your family again.

Good luck to you.
