Ontario ESA & OHSA Legislative Changes 2025: What Employers Need to Know

In recent years, the Ontario government has brought in a series of amendments to the Ontario Employment Standards Act (ESA) and Occupational Health & Safety Act (OHSA) to make the province a better place to work in.     

Key provisions from the latest installment of these amendments – the Working for Workers Four and Five Acts, 2024 (Bill 149 and Bill 190) – are coming into effect soon.  

Employers should act now to ensure compliance with these new Ontario ESA and OHSA changes to protect their business from huge fines and potential employee claims.  

This blog explains what the new regulations are, when they come into force, and what Ontario employers need to do to stay compliant. 

What are the new regulations affecting Ontario ESA? 

Mandatory terms and conditions of employment (Ontario Reg. 477/24) - Effective July 1, 2025 

Starting July 1, employers in Ontario with 25 or more employees must provide new staff with written details about their employment, generally before their first day of work.   

Employers will have to put in writing and share the following information with employees:
