[Regulatory Framework]What is needed to change older statutes that tend to be all-inclusive statements of...

Statutes—especially older, comprehensive ones—can only be amended or repealed by an act of the legislative authority that created them. In Canada, this means a provincial or federal legislature must formally pass a new act or amendment. Legislatures are the bodies responsible for enacting, revising, or modernizing statutory law to reflect new legal, social, or commercial developments.

Option B is incorrect because Canada does not change statutes through public votes (referenda), except in rare constitutional matters. Option C is incorrect and uses U.S. terminology (“congress”), which does not apply to the Canadian system. Even if compared to Parliament, a bill alone does not change a statute until it is passed into law by the legislature. Option D is incorrect because the Supreme Court interprets law, but does not rewrite statutes.

Thus, only an act of legislature can formally alter statutory law, making A the correct answer.
