Grande was a strong advocate for multiculturalism and multicultural services during his time. He supported minority language rights in education, and in 1986 he introduced a Private Member's Bill that would have made it easier for students to be taught in languages other than English or French. The bill died on the order paper when a new election was called in 1987. Grande was also an advocate for labour, and successfully represented three workers from a North York, Ontario factory before the Ontario Labour Relations Board in 1979-80. He also supported the rights of tenants, and promoted legislation to permit persons over sixteen years of age to gain access to their medical records.
