Poor performance can be a legitimate reason for an employer to end employment, but the circumstances surrounding dismissal determine whether it may amount to an unjustified termination. Employers generally have discretion to assess performance and make staffing decisions, yet they may still have obligations concerning notice, compensation, contracts, and applicable employment legislation. Problems can arise when an employer dismisses someone without adequate consideration of their employment agreement or provides an unsupported explanation. Understanding the difference between legitimate performance-based dismissal and an improper termination requires examining the employee’s history and surrounding workplace circumstances.
When Can Poor Performance Lead to an Unjustified Termination?
Performance Expectations Must Be Clear
Employees should generally understand what their employer expects regarding responsibilities, productivity, quality, attendance, and workplace conduct. If expectations were never communicated clearly, it may be difficult to determine whether alleged performance deficiencies were reasonable grounds for dismissal. Job descriptions, workplace policies, performance objectives, and written evaluations can provide useful evidence about expectations. An employer may identify genuine performance concerns, but inconsistent standards or unclear instructions can complicate the situation. Where dismissal follows vague or changing expectations, an unjustified termination may warrant closer examination of the employer’s decision and compliance with employment obligations.
Employers May Need Supporting Evidence
Documentation can be particularly important when poor performance is cited as the reason for dismissal. Performance reviews, written warnings, improvement plans, emails, meeting notes, and records of specific incidents may demonstrate how concerns developed over time. A sudden allegation of serious performance problems may raise questions when earlier evaluations were consistently positive or no concerns were communicated. However, every case must be assessed individually because employers may discover legitimate deficiencies at different stages. Employees should retain relevant records so an employment lawyer can compare the employer’s stated reason with the documented history.
Opportunity to Improve Can Matter
In some circumstances, an employer may provide an employee with feedback, guidance, or a reasonable opportunity to address identified performance concerns before termination. Whether such an opportunity was appropriate depends on the position, circumstances, employment agreement, and applicable legal principles. A performance improvement plan can establish measurable expectations and provide a record of discussions between the parties. Failure to follow an employer’s own established procedures may become relevant when assessing dismissal. If performance concerns appear to have been used as a pretext for another reason, the circumstances may support an unjustified termination claim.

Termination Pay Remains Important
Even when an employer genuinely believes an employee’s performance is inadequate, that does not necessarily mean the employee can be dismissed without notice or compensation. In Canada, the employer’s obligations may depend on the employment contract, applicable employment standards legislation, and common-law principles. An allegation of poor performance does not automatically establish cause for immediate dismissal. If the employer cannot legally justify termination without notice, the employee may still have potential entitlement to reasonable notice or pay instead. Employees should therefore distinguish between the employer’s reason for dismissal and its separate obligations when ending employment.
Discrimination or Retaliation Changes the Analysis
Performance concerns can sometimes overlap with protected workplace rights. For example, an employee may question whether negative performance allegations arose after making a workplace complaint, requesting an accommodation, or experiencing circumstances involving a protected human-rights characteristic. Timing, communications, performance records, and treatment compared with other employees may help establish the broader context. If the actual reason for dismissal was discriminatory or retaliatory, the matter may involve legal issues beyond ordinary wrongful dismissal. An unjustified termination should therefore be evaluated by considering both the employer’s stated explanation and the surrounding circumstances.

Assessing the Individual Circumstances
Ultimately, poor performance can contribute to a lawful dismissal, but it does not automatically eliminate an employee’s rights. An unjustified termination may arise where the employer fails to meet contractual or legal obligations, relies on an improper reason, or handles the dismissal in a manner inconsistent with applicable requirements. Employees should preserve performance evaluations, correspondence, employment contracts, and termination documents before accepting a settlement or signing a release. Obtaining independent legal advice can help determine whether the employer’s concerns were genuine, whether proper procedures were followed, and whether compensation or another remedy may be available.
