In Alberta common law spouses do not have property rights so you don't automatically share in assets the way that legally married spouses do.
Rather, the court would look at your contributions and you would get credit for what you and your parents paid towards the value of the house.
You will not have the right to remain living there because the house is his as it is in his name but he will have to pay you out.
He will not be able to get you out so fast and if this gets to court before 3 months which is unlikely you can prove that your parents need that time so no one will be hurt and the court will likely give it to you.
If you are financially dependent on him he will have to provide you with child support at least for a while.
So really your next step should be to consult with a family lawyer face to face.
You can contact the Law Society and use their Lawyer Referral Service. You will be given the name of a lawyer and can consult with the lawyer and the first half hour will be free.
