The procedure for amending the Constitution of Canada proves to be rather rigid. The Meech Lake Accord and the Charlottetown Agreement having failed in 1990 and 1992, it is generally felt that a significant constitutional reform has become impossible. Yet, several amendments have been made through the bilateral procedure permitted by section 43 of the Constitution Act, 1982, in spite of the fact that that section has received a narrow construction which greatly restricts its potential usefulness. This article questions such a construction and concludes that the bilateral procedure could arguably serve to insert new provisions into the Constitution of Canada. It also reviews the existing provisions of the Constitution that could be amended bilaterally in order to accommodate Quebec.
