When did S.O. 2020 c. 18, Schedule 1, sections 1-3 come into force?

The correct choice indicates that S.O. 2020 c. 18, Schedule 1, sections 1-3 came into force on July 21, 2020. This date is significant because it reflects the proper legislative timeline for when these specific sections became active and enforceable.

Understanding the context around this legislation helps clarify its impact and implementation. The date is important for professionals working within the Ontario Building Code framework as it establishes the lawful requirements and standards applicable from that date onwards. Knowing when regulations come into effect is crucial for compliance, as building projects initiated prior to this date might not be subject to the newer standards and could need to adhere to older regulations.

The other choices present dates that do not correspond to the enactment of these specific sections, which emphasizes the importance of accurate historical significance in regulating building standards.
