The Canadian governing code for pressure vessels is B51. This code, also known as the CSA B51 Boiler, Pressure Vessel, and Pressure Piping Code, is used to regulate and ensure the safety and quality of pressure vessels in Canada. Option B, A123, is incorrect because it is the American Society of Mechanical Engineers (ASME) code, not specific to Canada. Option C, C45, is incorrect because it is the Canadian standard for mechanical and structural tubing, not for pressure vessels. Option D, D78, is incorrect because it is not a recognized code or standard for pressure vessels in Canada.
