What can two or more principal authorities agree upon regarding building plans?

The ability for two or more principal authorities to agree upon reviews of building plans and specifications is crucial in ensuring that construction meets the standards set by the Ontario Building Code. This collaborative approach allows these authorities to conduct a thorough review for compliance, thereby ensuring the safety and integrity of buildings being constructed within their respective jurisdictions.

Through this agreement, the principal authorities can align their evaluations and potentially streamline the process for applicants, reducing redundancy and improving efficiency in compliance checking. This is particularly beneficial in cases where projects span multiple jurisdictions, as it promotes a unified standard of safety across various locations.

In contrast, options suggesting the sharing of resources or joint approval of all projects do not capture the primary function of the authorities under the Ontario Building Code, as these activities may not typically fall within their defined roles or legal frameworks. Likewise, the statement about jurisdictions does not apply, since principal authorities are often able to recognize and assist each other rather than being completely independent.
