“Allowing same-sex couples to choose their partners and to celebrate their unions is not an adequate substitute for legal recognition. This is not a case of the government balancing the interests of competing groups. Allowing same-sex couples to marry does not result in a corresponding deprivation to opposite-sex couples.
Nor is this a case of balancing the rights of same-sex couples against the rights of religious groups who oppose same- sex marriage. Freedom of religion under s. 2(a) of the Charter ensures that religious groups have the option of refusing to solemnize same-sex marriages. The equality guarantee, however, ensures that the beliefs and practices of various religious groups are not imposed on persons who do not share those views.
In our view, the opposite-sex requirement in the definition of marriage does not minimally impair the rights of the claimants. Same-sex couples have been completely excluded from a fundamental societal institution. Complete exclusion cannot constitute minimal impairment.”
