Unfair Labour Practice Lawyer for Ontario and BC Employers
Served with an unfair labour practice complaint? These proceedings move fast, the labour boards' remedial powers are broad, and a mishandled response can lead to orders, reinstatement, or even remedial certification of a union. Achkar Law's labour lawyers defend employers before the Ontario and BC Labour Relations Boards. Get advice immediately.




An unfair labour practice is conduct by an employer or union that violates the rights protected under provincial labour relations legislation. For employers in Ontario, unfair labour practices are governed by the Labour Relations Act, 1995 and adjudicated by the Ontario Labour Relations Board. In British Columbia, they are governed by the BC Labour Relations Code and adjudicated by the BC Labour Relations Board. When a complaint is filed against your organization, the proceedings move quickly, the board's remedial powers are broad, and the early decisions tend to lock in consequences that are hard to undo.
The board can order reinstatement of employees, require the employer to cease and desist from specific conduct, impose financial remedies, and in serious cases order a first collective agreement or grant remedial certification of a union. Employers who respond without experienced labour law counsel are at a significant disadvantage from the outset. Achkar Law's labour lawyers represent employers across Ontario and British Columbia in responding to unfair labour practice complaints, building strong defences, and protecting the organization's position before both provincial labour boards.

Common Unfair Labour Practice Allegations Against Employers in Ontario and BC
Unfair labour practice complaints against employers typically arise in the context of union organizing, collective bargaining, or the administration of an existing collective agreement. These are the most common categories employers face.
Interference with union organizing
Employers are prohibited from interfering with, restraining, or coercing employees in the exercise of their right to join a union or participate in union activities. Conduct during an organizing campaign that crosses this line, including threats, promises of benefit, or surveillance of organizing activity, can form the basis of a complaint. Note that statements by supervisors are generally treated in law as statements by the employer.
Retaliation for union activity
Disciplining, terminating, or otherwise penalizing an employee because of their union membership or activity is a classic unfair labour practice. In Ontario and BC there is a reverse onus in certain circumstances, meaning the employer must demonstrate that its action was not motivated by the employee's union activity.
Failure to bargain in good faith
Both provinces require employers to bargain collectively in good faith and make every reasonable effort to reach a collective agreement. Allegations of surface bargaining, deliberately delaying negotiations, or making proposals designed to frustrate agreement can support a bad faith bargaining complaint before the board.
Unilateral changes to working conditions
Once a bargaining relationship is established, employers are generally prohibited from making unilateral changes to wages, hours, or working conditions without bargaining with the union. Changing employment terms without the union's agreement during bargaining or the life of a collective agreement can constitute an unfair labour practice.
Domination or control of a union
Employers are prohibited from participating in or interfering with the formation or administration of a union, or contributing financial or other support to it. Conduct that gives the appearance of employer influence over a union's internal affairs can form the basis of a domination complaint.
The first days shape the outcome
Unfair labour practice proceedings before both boards are governed by strict timelines. The board can move quickly from the filing of a complaint to a hearing, and early strategic decisions have significant implications for the result. Employers who respond without experienced counsel frequently make avoidable procedural and substantive errors that weaken their position, and the strength of a defence depends heavily on the quality of the response filed and the strategy adopted from the first day the complaint is served.
How Employers Defend Against Unfair Labour Practice Allegations
A well-prepared defence addresses both the factual record and the applicable legal framework. These are the most important elements of an effective employer response in Ontario or BC.
Legitimate business reason
Where an employer's action is alleged to have been motivated by anti-union animus, one of the strongest defences is establishing that the action was taken for a legitimate, non-discriminatory business reason unrelated to the employee's union activity. A thorough documentation review and a clear evidentiary record of that business reason are essential, particularly given the reverse onus.
Challenging the factual record
Many complaints rest on a characterization of events that does not accurately reflect what occurred. A detailed review of documentation, communications, and witness accounts can identify inconsistencies in the complainant's version and build a compelling counter-narrative for the board.
Procedural challenges
Unfair labour practice complaints must be filed within specific time limits in both provinces. Complaints filed outside the applicable limitation period can be dismissed on procedural grounds, and other procedural defences may be available depending on how the complaint is framed.
Good faith bargaining evidence
Where a complaint alleges bad faith bargaining, a detailed evidentiary record of the employer's conduct at the table is critical: proposals made, counterproposals considered, the pace of negotiations, and genuine efforts to reach agreement. A well-documented bargaining history is the most effective answer to a surface bargaining allegation.
Consistent application of rules
Where discipline or termination of a union-involved employee is challenged as retaliatory, showing that the employer applied its rules consistently across all employees, regardless of union involvement, is a powerful defence. Documentation of how similar conduct by other employees was treated strengthens the argument.
Settlement and early resolution
Not every complaint is best resolved through a full hearing. In some cases, early negotiated resolution through mediation or settlement produces a better outcome than a contested proceeding. We assess each complaint on its merits and advise whether settlement or full litigation better serves the organization.

Labour board proceedings and hearings

Unfair Labour Practice in Ontario and BC: Common Questions
What is an unfair labour practice in Ontario?
An unfair labour practice in Ontario is conduct by an employer or union that violates the rights protected under the Labour Relations Act, 1995. For employers, common examples include interfering with union organizing, retaliating against employees for union activity, failing to bargain in good faith, making unilateral changes to working conditions during bargaining or the life of a collective agreement, and dominating or controlling a union.
Complaints are filed with and adjudicated by the Ontario Labour Relations Board, which has broad remedial powers and can order employers to cease prohibited conduct, reinstate terminated employees, and pay compensation.
What is an unfair labour practice in BC?
In British Columbia, unfair labour practices are governed by the BC Labour Relations Code and adjudicated by the BC Labour Relations Board. The BC provisions are similar in scope to Ontario's but operate under a distinct legislative framework with some procedural and substantive differences, so BC employers need counsel with specific BC Labour Relations Board experience. Achkar Law's labour lawyers advise and represent employers before the BC board.
What should an employer do immediately after receiving a complaint?
Contact an experienced labour lawyer right away. Do not respond to the complaint, make public statements about it, or take any action that could be seen as further interference with union rights before getting legal advice. Preserve all documents, communications, and records relevant to the allegations.
Labour board proceedings run on tight timelines and the employer's response must be filed promptly. We can assess the complaint and advise on the response strategy within a very short timeframe.
Can an employer file an unfair labour practice complaint against a union?
Yes. Employers can file complaints against unions in both Ontario and BC. Common employer complaints include union interference with management rights, union failure to bargain in good faith, union coercion of employees, and breach of a no-strike provision during the life of a collective agreement. We advise employers on both defending complaints and, where warranted, pursuing them against a union.
What are the possible outcomes of an unfair labour practice proceeding?
If a complaint is upheld, the board can order a range of remedies against the employer: cease and desist orders, reinstatement of employees dismissed or disciplined in connection with the complaint, compensation for lost wages and benefits, and in serious cases remedial certification of a union or imposition of a first collective agreement. A strong defence, built on a thorough factual record and experienced representation, significantly improves the prospects of a favourable outcome, whether through dismissal, settlement, or a successful hearing.
