What is the Clarity Act?

The Clarity Act (officially An Act to give effect to the requirement for clarity as set out in the opinion of the Supreme Court of Canada in the Quebec Secession Reference) is a federal statute that sets out the federal framework for any future negotiation of provincial secession from Canada. The Clarity Act was introduced by Justice Minister Stéphane Dion on December 13, 1999, received Royal Assent on June 29, 2000, and remains in force.

The Act has three principal provisions. First, before any federal negotiation begins, the House of Commons must determine that a referendum question on secession is 'clear' (the question must address only secession, not associated issues). Second, after a referendum, the House of Commons must determine whether a majority result constitutes a 'clear expression' of the will of a province's population on secession. Third, negotiation of secession would address the division of assets and debts, changes to boundaries (including potential partition of Quebec to keep federalist regions in Canada), Indigenous rights, minority rights, and international obligations.

The Act was the federal government's response to the 1998 Reference re Secession of Quebec. The Reference held that any future secession would require a 'clear majority on a clear question' and would trigger a federal-provincial duty to negotiate. The Clarity Act operationalises these Reference requirements by giving the federal House of Commons the authority to determine whether those conditions are met. The Act gives Indigenous peoples a particular role: the House of Commons must consider Indigenous interests, and any secession negotiation must address Indigenous rights.

The Act has been controversial in Quebec. Quebec's National Assembly passed Bill 99 (the Act respecting the exercise of the fundamental rights and prerogatives of the Québec people and the Québec State, in force December 7, 2000) rejecting the Clarity Act's claim of federal authority over secession procedure. The Quebec Court of Appeal upheld the constitutional validity of Bill 99 in Henderson v. Quebec (Procureur général) (2018). The Supreme Court of Canada has not yet ruled on the relationship between the federal Clarity Act and Quebec's Bill 99. The Clarity Act has not been formally invoked since its 2000 passage because no province has held a sovereignty referendum during this period. Quebec sovereignty support has fluctuated since 1995 but has not reached majority levels in any consistent polling.
