Ontario Employment Standards Act (ESA)
How Ontario's provincial employment standards differ from the federal Canada Labour Code
Content last verified against official statutes: March 30, 2026
Am I Provincially Regulated?
If your employer is NOT in banking, telecom, broadcasting, interprovincial transportation, or federal Crown corporations, you are almost certainly provincially regulated. This includes retail, restaurants, tech companies, healthcare, construction, manufacturing, education, and most private-sector employers based in Ontario.
Overtime
Ontario calculates overtime differently from the federal CLC. The threshold is 44 hours per week, not 40. There is no daily overtime threshold (unlike BC and federal). This means you can work 10-hour days without triggering overtime, as long as your weekly total stays under 44 hours. Overtime rate is the same: 1.5x your regular rate. Employers can offer time off in lieu at 1.5 hours per overtime hour, but only with a written agreement.
Key difference from federal: The 44-hour weekly threshold means Ontario workers earn less overtime than federal workers doing the same hours. If you work exactly 42 hours in a week, you get zero overtime in Ontario but 2 hours of overtime under the CLC.
Sick Leave
Ontario provides 3 paid sick days per year (effective since 2022) plus 3 unpaid sick days, for a total of 6 days per calendar year. You qualify after being employed for at least 2 consecutive days. Like the CLC, your employer cannot ask why you are sick, only that you are unfit for work. A doctor's note can only be required in reasonable circumstances.
Key difference from federal: Ontario's 3 paid + 3 unpaid = 6 total days. Federal provides 3 paid + 7 unpaid = 10 total days. Ontario workers get fewer total days.
Termination & Severance
Notice of termination based on length of service: 1 week (under 1 year), 2 weeks (1-3 years), 3 weeks (3-4 years), up to 8 weeks (8+ years) under ESA s.57.
Severance pay: In addition to notice, you may be entitled to severance pay if your employer's payroll is $2.5 million or more, or you have 5+ years of service. Severance is calculated at 1 week per year of service, up to 26 weeks.
Key difference from federal: Federal CLC s.240 provides unjust dismissal protection (employer must prove just cause after 12 months). Ontario has NO equivalent statutory unjust dismissal protection. Ontario workers rely on common law wrongful dismissal claims, which provide compensation but NOT reinstatement. This is a significant gap.
Reprisal Protection
ESA s.74 prohibits employers from penalizing employees for exercising ESA rights (asking about pay, taking leave, filing complaints). However, Ontario does not have the federal reverse burden of proof (CLC s.246.1(4)). In Ontario, the burden of proving reprisal rests more heavily on the employee, though the Ontario Labour Relations Board can draw inferences from circumstantial evidence.
Key difference from federal: No automatic reverse onus. You carry more of the proof burden in Ontario.
Harassment
Ontario addresses workplace harassment through two statutes. Occupational Health and Safety Act (OHSA) s.32.0.1 defines workplace harassment (including sexual harassment) and requires employers to have policies, investigate complaints, and protect workers. Ontario Human Rights Code protects against discrimination-based harassment. File with the Human Rights Tribunal of Ontario (HRTO) within 1 year of the last incident.
Key difference from federal: Ontario's OHSA framework is separate from human rights. Federal workers use SOR/2020-130 which combines both harassment and violence in one framework.

When Should You Contact a Lawyer?
This platform is designed to help you build your case independently — collecting evidence, documenting incidents, writing complaints in compliance language, and navigating the internal HR process. Many employees can handle these steps without a lawyer.
The most effective time to engage a lawyer is after you have completed the internal process and your employer has failed to resolve your complaint. At that point, a lawyer can review your complete file — your timeline, evidence, complaint, and the employer's response — and provide strategic advice before you file with an external body such as the CIRB, CHRC, or OPC.
By doing the groundwork yourself, your consultation becomes a focused strategic review rather than a costly fact-gathering session. This approach has been validated by employment lawyers who reviewed files prepared using this methodology and found the documentation thorough with nothing to add.
