The time that my parents applied for Provincial Nominee and me , as their dependant child, me and my partner were living in the same house with my parents
You would have qualified as common law partners back when you got your PR. However, you have two problems here.
1. You did not include your partner on your application and to immigration, that is misrepresentation. It doesn't matter to immigration that you did not know. The instructions are on the CIC website and you had the same opportunity to read them as everybody else.
2. Even if you had included your partner on your application back then, in most cases, that would have meant that you would no longer have been seen as a dependent child and would not have been eligible to get PR with your parents and would have been removed from their application.
In order to avoid problems with your PR, you can never admit that you and your partner lived together for 2 years during your PR processing time. You can say you lived together for a few months but definitely no more than a year because that would have meant you would have had to add your partner to your application.
You have three options to sponsor your partner now.
A. One is getting married, in Canada if your partner can get a visit visa or in a 3rd country that allows same sex marriages if you can both get a visit visa to there.
B. Another is that you try to qualify for common law again, either by your partner trying for a visit visa to Canada to stay with you or you going back to the Philippines for 1 year. You must however be in Canada when you apply for sponsorship and you must reside in Canada during the processing time.
C. A third would be to apply as conjugal partners. This would involve showing that you have a marriage like relationship but laws/culture and immigration barriers prevent you from getting married or living together to qualify for common law. Same sex relationships usually have a good chance to be approved under this class. However, your application would be stronger if you could show that your partner was denied a visit visa to Canada, thereby preventing you from marrying or living together in Canada.
