Hi,how do you define 'declare relationships'(do people go to some organizations and officially disclose the relationship?)
If someone who has applied for a PR visa gets married or starts to live with someone or has a child, before the PR visa is issued and the person goes to Canada, the spouse/partner/child must be declared to CIC. The applicant must let the visa office processing his/her file know about the new family member. If he/she gets a PR visa and lands in Canada without telling CIC about the change in family, he/she will never be able to sponsor that person.
Since me and my husband were living together on and off before we've got married, he usually lived with his family in Toronto when we were dating, so we did not declare common-law relationship when I filed my PR application, and I've got my PR, then we married.
If you had lived with him for a year, you should have declared him as your common-law spouse. Since you just lived with him off and on, CIC won't consider that a common-law relationship, so you should be safe.
Will that be any problem if I sponsor him in the near future? Thank you!
There should be no problem to sponsor him soon. But there may be a problem if you wait 3 years: if you two are living together in some other country for 3 years, then fine (as long as your PR is still valid), but if you are in Canada and he is somewhere else, CIC will be suspicious about why it took you so long to sponsor him.
