On June 9, 1994, Perruzza was one of twelve New Democratic Party MPPs to vote against Bill 167, legislation that would have provided same-sex couples with rights and obligations (including family benefits) equal to opposite-sex common law couples. The NDP had officially endorsed the bill, but allowed the issue to be decided by "free vote". The bill was defeated by a vote of 68-59. If the twelve dissenting New Democratic Party MPPs had voted for the motion, it would have passed.
