The escalating Canada-U.S. tariff dispute is no longer simply a trade-policy story. For Canadian businesses and workers, it is increasingly an employment law issue.

Following the breakdown of Canada-U.S. trade negotiations, new U.S. tariffs have taken effect on billions of dollars of Canadian goods, while Canada has announced retaliatory measures. As CTV News reports, the effects of the trade dispute are being felt on both sides of the border.

For Ontario employers that manufacture goods, export to the United States, import American components or operate within integrated North American supply chains, prolonged tariffs can mean higher costs, reduced orders and considerable uncertainty.

For employees, those pressures can translate into reduced hours, temporary layoffs, restructuring and, in more serious cases, permanent job losses.

The important point is that economic uncertainty does not eliminate an employer’s employment law obligations.

Why Tariffs Can Become an Employment Law Problem

Canada and the United States have deeply integrated economies. Ontario businesses in sectors such as manufacturing, automotive, steel and aluminum, construction materials, transportation, agriculture and related supply chains can be particularly sensitive to changes in cross-border trade.

A significant tariff can make a Canadian product substantially more expensive for an American customer. Canadian businesses may also face increased costs where they rely on U.S. inputs subject to Canadian retaliatory tariffs.

Businesses responding to these pressures may consider:

  • reducing overtime or employee hours;
  • implementing hiring freezes;
  • temporarily reducing production;
  • temporarily laying off employees;
  • reducing compensation or changing duties;
  • restructuring operations; or
  • permanently eliminating positions.

Each option can have different consequences under Ontario employment law.

Can an Ontario Employer Temporarily Lay Off Employees Because of Tariffs?

A temporary layoff may seem like an attractive solution where an employer believes a decline in business will be short-lived.

However, employers should proceed carefully.

The Ontario Employment Standards Act, 2000 (the “ESA”) establishes circumstances in which a layoff can remain temporary rather than becoming a termination for statutory purposes. But compliance with the ESA does not necessarily resolve the separate question of an employee’s rights under their employment contract or at common law.

Depending on the employment agreement and history between the parties, an employer may not have a contractual right to temporarily lay off an employee.

A unilateral layoff may therefore potentially amount to a constructive dismissal, even where the employer intends to recall the employee when economic conditions improve.

Employees facing a layoff should generally avoid assuming that the word “temporary” determines their legal rights. The employment agreement, workplace history, duration of the layoff and surrounding circumstances can all matter.

For more information, see Pelsmakher Law’s guide to wrongful and constructive dismissal and our constructive dismissal services.

Pay Cuts, Reduced Hours and Constructive Dismissal

Employers facing tariff-related pressures may also attempt to preserve jobs by reducing payroll costs rather than terminating employees.

That can be a sensible business objective, but significant unilateral changes to employment terms can create legal risk.

For example, a substantial reduction in an employee’s:

  • salary;
  • hours of work;
  • commissions or incentive compensation;
  • responsibilities;
  • position or status; or
  • other fundamental employment terms

may potentially amount to constructive dismissal.

Whether a particular change crosses that threshold is highly fact-specific.

For employees, this is also an area where acting too quickly can be problematic. An employee who believes they have been constructively dismissed should generally obtain legal advice before resigning, because resignation can affect the employee’s legal position.

Tariff-Related Terminations Still Require Notice or Pay

If economic conditions ultimately cause an employer to eliminate positions, describing the decision as a “restructuring,” “tariff response,” “lack of work” or “cost reduction” does not ordinarily eliminate termination obligations.

An employer can generally terminate employment without cause for legitimate business reasons, but it must still comply with applicable employment standards legislation, the employment contract and, where applicable, the common law.

For most provincially regulated Ontario employees, the ESA establishes minimum termination requirements. Some employees may also qualify for statutory severance pay.

Those statutory amounts are only the starting point.

Unless an enforceable employment agreement validly limits the employee’s entitlements, a terminated employee may potentially be entitled to significantly greater common law reasonable notice or damages in lieu of notice.

Factors relevant to reasonable notice can include the employee’s age, length of service, character of employment and availability of comparable employment.

Pelsmakher Law recently addressed these distinctions in greater detail in Termination Pay, Severance Pay and Reasonable Notice in Ontario: What Employees Are Actually Entitled To.

A Difficult Job Market Can Matter to Severance

An extended Canada-U.S. trade dispute could also have a less obvious consequence for dismissed employees: finding comparable employment may become more difficult in industries experiencing widespread contraction.

Common law reasonable notice is intended, in part, to provide an employee with a reasonable period to secure comparable employment.

There is no automatic “tariff premium” added to a severance package. However, the availability of comparable employment is one of the circumstances courts may consider when determining reasonable notice.

A widespread downturn affecting an employee’s particular industry, occupation or geographic labour market may therefore become relevant in an individual wrongful dismissal case.

Employees should not assume that an employer’s initial severance offer necessarily represents their complete entitlement. See How Much Severance Am I Really Entitled to in Ontario? for a further explanation.

What Happens if Tariffs Lead to Mass Terminations?

Large-scale restructuring can trigger additional obligations.

Under Ontario’s ESA, special mass termination provisions can apply where an employer terminates 50 or more employees at an establishment within a four-week period, subject to the legislation’s requirements and exceptions.

Where those provisions apply, statutory notice can increase depending on the number of affected employees:

| Employees Terminated | ESA Mass-Termination Notice | | 50–199 | 8 weeks | | 200–499 | 12 weeks | | 500 or more | 16 weeks |

Employers may also have additional procedural and disclosure obligations when carrying out a mass termination.

Importantly, these are minimum statutory requirements. They do not necessarily replace an employee’s potentially greater contractual or common law rights.

Economic Hardship Does Not Automatically Reduce Severance

One misconception that can arise during an economic downturn is that an employer experiencing financial difficulty can simply reduce the severance otherwise owed to an employee.

Generally, the reason for a without-cause termination does not determine the employee’s basic entitlement to notice.

A business may have entirely legitimate economic reasons for reducing its workforce. That does not, by itself, transform the termination into cause or eliminate statutory, contractual or common law termination obligations.

As discussed in “Your Role Has Been Eliminated” — Do You Still Get Severance?, restructuring and redundancy generally explain why employment ended; they do not necessarily determine what the employee is owed.

What Should Employers Be Thinking About?

For employers exposed to Canada-U.S. trade uncertainty, workforce planning should occur alongside employment-law planning.

Before implementing layoffs or significant cost-saving measures, employers should review employment agreements to determine whether they permit temporary layoffs or other proposed changes. Employers contemplating permanent reductions should assess statutory notice and severance obligations, potential common law exposure, benefit continuation, bonus and commission obligations, and whether the mass-termination provisions may apply.

Where reductions are expected to occur in stages, employers should also consider the overall timing and number of affected employees rather than viewing each termination in isolation.

Careful planning can help businesses respond to economic pressure without unintentionally converting a temporary cost-saving measure into a constructive dismissal claim or creating avoidable liability during a larger restructuring.

What Should Employees Do?

Employees affected by tariff-related restructuring should distinguish between an employer’s business explanation and the employee’s legal entitlement.

If you have been temporarily laid off, had your compensation or hours substantially reduced, or received a termination package, review your employment agreement and the proposed terms carefully before accepting the change or signing a release.

In particular, employees should consider whether:

  • the employer had the right to impose a temporary layoff;
  • changes to compensation or duties could amount to constructive dismissal;
  • the termination package satisfies ESA requirements;
  • statutory severance pay applies;
  • a mass termination has occurred;
  • the employment contract validly limits termination entitlements; and
  • additional common law reasonable notice may be available.

The Employment Law Consequences May Outlast the Tariffs

The ultimate direction of the Canada-U.S. trade dispute remains uncertain.

What is clearer is that prolonged trade disruption can move quickly from the balance sheet to the workplace. Businesses may have to make difficult decisions about production, staffing and compensation, while employees may face temporary layoffs, reduced working conditions or termination.

Ontario employment law continues to apply throughout that uncertainty.

For employers, early planning can help reduce legal exposure while preserving flexibility. For employees, understanding the difference between a temporary business measure and a potential dismissal can be critical before accepting changes, resigning or signing a severance package.

Frequently Asked Questions

Can my employer temporarily lay me off because of U.S. tariffs?

Possibly, but the fact that an employer is experiencing economic pressure does not necessarily give it a contractual right to lay off an employee. A temporary layoff can potentially constitute constructive dismissal depending on the employment agreement and circumstances, entitling you to a severance.

Can my employer reduce my salary or hours instead of laying me off?

An employer may propose limited changes to preserve employment, but a significant unilateral reduction in compensation, hours or other fundamental employment terms can potentially constitute constructive dismissal. The particular circumstances matter.

Am I entitled to severance if my job is eliminated because of tariffs?

Potentially, yes. A tariff-related restructuring does not generally eliminate an employee’s termination rights. Employees may have statutory, contractual and/or common law entitlements depending on their circumstances.

Does a company’s financial difficulty reduce what it owes terminated employees?

Not automatically. Financial difficulty may explain the business reason for a termination, but employers must still comply with applicable employment standards and contractual obligations pertaining to terminations, and employees may retain common law rights.

What happens if an employer lays off many employees at once?

Ontario’s mass-termination provisions may apply where 50 or more employees are terminated at an establishment within a four-week period, subject to statutory requirements and exceptions. Enhanced notice and additional employer obligations can result.

Should I sign a severance package if my employer says the termination is because of tariffs?

Employees should consider obtaining legal advice before signing a release. An employer’s explanation for the termination does not necessarily establish the employee’s full entitlement to notice, termination pay or severance.
