Quick Overview (TL;DR:)

Employers in Ontario can generally require employees to return to the office, but that right is not unlimited. Whether a return-to-office mandate is enforceable depends on the terms of your employment agreement, the nature of your remote work arrangement, and any applicable human rights accommodations. In some cases, requiring an employee to return to the office may amount to constructive dismissal if it fundamentally changes a key term of employment.

Back to the office

Recently, employers have been issuing return to office mandates requiring employees to return to work in the office either part-time or on a full-time basis. Return to office mandates have varied across different businesses, with some requiring full-time office attendance, phased-in attendance, or a hybrid approach, and companies have adopted different approaches for different reasons, including productivity, collaboration, lease obligations, and flexibility concerns. However, can an employer require an employee to return to the office? A return to office plan is usually more effective when employers clearly communicate it, explain the reasons for the change, and manage the transition in a way that recognizes employee anxieties.

In many cases, employers can require employees to return to the office. However, that right is not unlimited. Whether a return-to-office mandate is enforceable depends on the employee’s employment agreement, how long they have worked remotely, whether remote work became a fundamental term of employment, and whether human rights or accommodation obligations apply. For employees and employers in Ontario, these issues can affect whether a refusal may lead to discipline, whether a new policy could support a constructive dismissal claim, and how to respond to a return-to-office mandate lawfully and strategically.

Types of Return to Office Arrangements

Return to office mandates vary widely among many organizations. Some employers require employees to be in the office full time, while others adopt a hybrid schedule that combines remote work with in-office days. Common arrangements include a set week in office, such as four days in the office and one remote day per week. These flexible models aim to balance productivity with employee preferences and health considerations.

Are return to office mandates legal in Ontario?

Generally, yes. Return to office mandates are legal in Ontario provided that they abide by:

an employee’s existing employment agreement
the Employment Standards Act
the Human Rights Code
any contractual obligations owed to the employee

Simply requiring employees to return to office in person is not in itself unlawful.

When can an employer require employees to return to office?

An employer can require an employee to return to office if:

the employment agreement specifies an in-office work location
the contract provides the employer with the power to change your work location
remote work was temporary

Each employee’s situation is different and depends on the specific employment relationship and contract.

Can employees refuse a return to office mandate?

Sometimes. Employees have the right to refuse a return to office mandate in certain circumstances, though many employees may have room to seek flexibility before refusing outright.

For example:

An employer cannot legally ask an employee to return to work in the office if the employee’s contract specifically states that they are a remote worker.
If the employee has worked remotely for a long period of time and the remote work becomes a core component of the position
If the employee has a Human Rights accommodation that requires them to work remotely to satisfy the accommodation.

Where refusal is not clearly justified, employees can still negotiate hybrid work arrangements during the transition, and keeping them informed about what is expected and what remains flexible can reduce anxiety.

Outside of these exceptions, employers generally can require an employee to return to the office to work.

When does a return to office policy become constructive dismissal?

A return to office policy may constitute constructive dismissal if the change represents a significant and unilateral change to a key term of employment.

Examples include:

Requiring an employee who has been working remotely for several years before a sudden mandatory full-time office attendance policy is put in place.
Imposing changes to job description and responsibilities because of a return to office policy, without the employee’s consent

For constructive dismissal to be asserted, there has to be a significant change in the employee’s work situation that the employee did not consent to. If constructive dismissal is established, the employer may owe full severance pay. Employees should not sign severance-related documents before getting legal advice, especially if the employer is threatening discipline for non-compliance.

Does working from home for several years change your rights?

Potentially.

It depends on the circumstances. The longer an employee has worked remotely, and the more that arrangement became part of the employment relationship, the stronger the argument that remote work has become an implied contractual term.

This is highly fact specific.

What should employees do before refusing to return to office?

Employees should avoid assuming they can simply refuse a return-to-office mandate.

Instead they should:

review their employment agreement and keep copies of relevant emails announcing the new office attendance requirements
determine whether remote work was contractually guaranteed
consider whether accommodation rights apply
seek legal advice before resigning or refusing to attend work

They should also consider the practical impact of returning, including commuting costs, lost time, environmental stress, and reduced flexibility for appointments and errands, before deciding on next steps.

Legal advice can help employees understand their next steps and what support is available.

Return to Office Trends Across Canada

Across Canada and Ontario, many organizations are navigating the evolving landscape of return to office (RTO) mandates. While some sectors, including government agencies and public service, emphasize full-time office attendance, others continue to support hybrid or remote work models.

In Ontario, the provincial government had set clear timelines for the public service, requiring employees to work in the office four days per week by October 2025 and full-time by January 2026. This phased approach reflects the employer’s responsibility to provide proper notice, which also signals efforts to balance operational needs with employee health, productivity, and work-life balance.

The public sector faces unique challenges, including office space shortages affecting approximately 60,000 workers and morale concerns amid crowded and shared workspaces. Meanwhile, private employers across Canada are implementing varied RTO mandates based on factors such as collaboration goals, lease obligations, and executive preferences.

These trends highlight the ongoing debate about the future of work, where employers weigh the benefits of in-person interaction, such as mentoring, spontaneous brainstorming, and clearer work-life boundaries, against employee preferences for flexibility. Legal considerations also play a significant role, as return to office policies must comply with employment agreements, human rights accommodations, and avoid triggering constructive dismissal claims.

Overall, the return to office landscape in Canada and Ontario continues to evolve, with diverse approaches reflecting sector-specific needs and a growing emphasis on managing transitions thoughtfully to support both organizational objectives, legal responsibilities and employee well-being.
