As with other parliamentary procedures in the House, members of opposition parties must place questions through the Speaker, addressing them only indirectly to the minister responsible for the issue at hand. When asking questions, members address the Speaker as "Mr. Speaker" or "Madam Speaker" (""Monsieur le président"" or ""Madame la présidente"" in French). There is no obligation for the minister referred to in the question to actually respond, and often the minister's parliamentary secretary or a fellow cabinet member will rise to answer the question. This is particularly true when the minister addressed is not actually present in the House during Question Period, and arguably occurs most often when the Prime Minister is addressed on a specific issue for which one of his ministers has more information.
