The Occupational Health and Safety Act (OHSA) in Canada is a cornerstone of workplace legislation, defining the rights and duties of employers, supervisors, and workers to ensure everyone comes home safely. It establishes the internal responsibility system (IRS) where all workplace parties share accountability for safety.
The Occupational Health and Safety Act (OHSA) in Canada is the primary legislation designed to protect workers from hazards on the job, operating under a system where each province and territory has its own specific Act. These laws create the internal responsibility system (IRS), mandating that employers, supervisors, and workers all share responsibility for health and safety in the workplace, moving beyond a simple set of rules to a proactive safety culture.
This legislative framework is critical for industries like construction where safety risks are inherently higher. Compliance with OHSA is not just a legal requirement, but a core component of ensuring every team member is safe, aligning perfectly with Site App Pro’s mission to ensure all workers come home safely.
OHSA is the widely used abbreviation for the Occupational Health and Safety Act, representing the foundational legislation in each Canadian jurisdiction that governs workplace safety. Specifically, OHSA provides a comprehensive framework detailing the mandatory duties, responsibilities, and rights of everyone involved in a workplace, from the owner to the newest employee, ensuring a legally enforceable standard for occupational health and safety.
Three Territorial Jurisdictions: Each of the three territories has its own specific OHS Act.
The Acts generally outline:
Understanding which OHSA applies to your business is the critical first step toward compliance.
No, the entity formally known as OSHA Canada does not exist; the acronym OSHA (Occupational Safety and Health Administration) refers to the federal agency that oversees workplace safety standards in the United States, which is a common source of confusion for Canadian businesses. While Canada’s OHSA legislation shares the goal of protecting workers with the American OSHA, they are entirely separate legal frameworks, meaning Canadian businesses must strictly follow their applicable Canadian OHSA.
The distinction between OSHA vs OHSA is purely geographical and jurisdictional: OHSA refers to the Canadian legislation that mandates workplace safety, while OSHA is the US federal agency responsible for setting and enforcing US safety standards. This is a crucial clarification for any business operating in Canada, particularly those in sectors that may have international ties, as strict compliance with the local Canadian OHSA is non-negotiable.
Safety management software like Site App Pro assist Canadian companies by providing the digital tools to easily document compliance with their respective Canadian OHSA requirements.
Receiving an OHS certificate typically refers to acquiring certification in a specific area of occupational health and safety or a formal recognition of compliance/competence, such as the Certificate of Recognition (COR) or a certification for Joint Health and Safety Committee (JHSC) members. Unlike a simple course completion, these OHS certificates represent a validated level of knowledge, skill, or a recognized standard of a company’s safety program.
Note: These requirements are specific to provinces like Ontario, where certification is legally mandated for certain workplaces.
The primary way to secure any credible OHS certificate is through approved, rigorous OHS training online or in person, ensuring that the certification is recognized by the relevant provincial body.
OHSA training in Canada consists of mandatory educational programs designed to provide workers, supervisors, and employers with the necessary knowledge to identify, assess, and control workplace hazards, ensuring they can fulfill their duties under the Act. While the exact course content and legislative references vary by province, all training must align with the foundational requirements of the specific provincial OHSA that governs the workplace.
The goal of this training is to equip every workplace party to implement the internal responsibility system (IRS), moving your team from simply asking, "Is this safe?" to proactively managing safety risks and documenting them, a task made simpler with a safety management app.
The requirements of OHSA are the legally binding duties and responsibilities that must be upheld by every workplace party (employers, supervisors, and workers) to maintain a safe working environment and ensure compliance. These requirements are extensive and can be found in the specific OHS Act and its accompanying regulations for your jurisdiction such as Ontario, Alberta or British Columbia.
For industries like construction and manufacturing, this often translates to highly detailed regulations regarding machine guarding, scaffold safety, and hazardous energy control (Lockout/Tagout), demanding a comprehensive, digital solution for safety management.
A workplace achieves the requirements of OHSA through the consistent, proactive implementation of a robust, comprehensive, and well-documented Health and Safety Management System (HSMS) that fully integrates the principles of the internal responsibility system (IRS). This is a continuous process of planning, checking, acting, and documenting, not a one-time event, which is why digital safety tools are essential.
Use a digital safety management system: Implement safety management software, like Site App Pro, to digitize forms (hazard acknowledgements, inductions, inspections), track training, and maintain an easily searchable resource paper trail, making due diligence verifiable.
For construction safety, the requirements of the Occupational Health and Safety Act are heavily focused on preventing high-risk, high-consequence incidents specific to the sector, such as falls, trench collapse, struck-by incidents, and electrical hazards. Given the dynamic nature and constantly changing environment of construction sites, the OHSA regulations are exceptionally detailed and demand daily, documented compliance.
A tool like Site App Pro is purpose-built for this environment, allowing a Project Manager or Safety Manager to digitize site inductions, complete daily FLRAs on a mobile device, and instantly record equipment checks, providing an undeniable paper trail for all OHSA compliance efforts.

While the core principles of OHSA remain consistent (the Right to Refuse, Right to Know, and the IRS) the specific provincial occupational health and safety regulations for construction can vary significantly in their detail, making local compliance mandatory. This provincial variation is why a CEO or Safety Manager must be intimately familiar with the legislation in the jurisdiction(s) where their work is performed.
For companies operating across multiple provinces, such as a large construction company, a centralized safety management system is crucial. It ensures that standard company procedures are customized and applied according to the specific provincial regulation of the worksite, eliminating the headache of managing compliance across disparate systems.
Navigating the complexities of provincial OHSA legislation and achieving COR certification often requires expert guidance. We recommend contacting your provincial safety association or a certified OHS consultant to ensure your company is compliant and has the peace of mind that your teams are safe.
