Which authority can designate organizations for testing compliance with the building code?

The authority that is responsible for designating organizations for testing compliance with the building code is the Lieutenant Governor. This designation typically falls within the broader framework of building regulations and compliance in Ontario and underscores the importance of ensuring that building standards and practices meet the established codes for safety and functionality. The role of the Lieutenant Governor includes overseeing various statutory obligations, ensuring that regulatory bodies are established and maintained according to provincial laws.

Other options may have their respective roles within the building regulatory framework, but the designation of organizations for testing compliance is specifically a function of the Lieutenant Governor. Having this level of authority ensures a standardized and regulated approach to building compliance testing within the province.
