I'm very confused about your dates. If you only moved in together in February 2022, then you were not common law until February 2023.I became a PR and landed here myself in January 17, 2019.
We became officially together on January 5, 2022, and he moved in with us (my sister and mom) in February 2022.
Also, one thing to note is that he came here as a visitor on ETA, but COVID came around January of 2019, and since there were lockdowns and we both live in two separate areas (living with his aunt at that time and I was living with my mom and sister), I decided to have him move in with me. Fast forward, we were supposed to apply for restoration of his status but wasn't able to and when we hit year after he overstayed his ETA, I decided to sponsor him through FC common-law after cohabiting for a year.
Earlier I thought you said you moved together 2020. I know your statuatory declaration said 2019 which was wrong.
Dates are extremely extremely important. I think you are best to move foward with the lawyer reviewing absolutely everything you submit.
