I see nothing in the bill that excludes section 133 of the British North America Act. The Constitution Act, 1867 very clearly establishes that English and French are the official languages that may be used in Parliament. That right is reasserted in subsection 17(1) of the charter. I see nothing in this bill that extinguishes the right of any person to use the language of his or her choice before Parliament.
