Independent Liberal Members of Parliament (or of the Canadian Senate or a provincial legislative assembly) are typically former Liberal caucus members who were either expelled from the Liberal Party caucus or resigned the whip due to a political disagreement. More recent examples, include Don Johnston who sat as an Independent Liberal from January 18, 1988 until the adjournment of parliament due to his resignation from the Liberal caucus as a result of his support of the Canada–United States Free Trade Agreement which the party opposed, Jag Bhaduria who sat as an Independent Liberal from 1994 to 1996 following his expulsion from the Liberal caucus and Dennis Mills who briefly left the Liberal caucus in 1996 to sit as an "Independent Liberal" to protest the Liberal government's failure to abolish the Goods and Services Tax (GST).
