We were looking unto this too. Weve read it from the CA gov website.
"Although the intention of the conjugal partner category is to accommodate Canadians and permanent residents with foreign partners who can neither marry nor live together, the inability to marry cannot be an absolute requirement, since this could have the effect of “forcing” those couples to marry who may have chosen not to. Persons who have established and maintained a conjugal relationship for one year and who do not intend to marry might be conjugal partners if they have been unable to cohabit because of an immigration impediment or other serious barrier. The key to determining whether an individual is a conjugal partner is whether they are in a conjugal relationship with their sponsor and whether there is a compelling barrier to continuous cohabitation."
