Bill S-218 aims to amend the Constitution Act, 1982 concerning the notwithstanding clause. This clause allows provincial and federal governments to temporarily override certain rights guaranteed by the Canadian Charter of Rights and Freedoms.

The main provisions of the bill include changes to the conditions under which the notwithstanding clause can be invoked. This may involve additional requirements for its use, such as public consultations or detailed justifications.

The Constitution Act, 1982 would be amended to incorporate these new conditions and requirements related to the notwithstanding clause.

Provincial governments and the federal government would be directly affected by these changes, as they would impact their ability to invoke the notwithstanding clause. Canadian citizens might also be indirectly affected by changes to the protection of their rights.
