Executive Summary: Key Legal and Evidentiary Issues

• The judicial review challenged an arbitrator’s decision regarding the calculation of a unionized employee’s separation allowance.

• CBC argued the decision was unreasonable for adopting an earlier start date and declining to prorate part-time service.

• The court upheld the arbitrator’s interpretation of the collective agreement, finding it fell within a reasonable range of outcomes.

• Claims of procedural unfairness due to exclusion of viva voce evidence were rejected as the process was agreed to be based on written submissions.

• Evidence of alleged past practices lacked sufficient proof of union awareness and acquiescence, defeating the estoppel argument.

• The court emphasized deference to experienced labour arbitrators in interpreting collective agreements.

Background and collective agreement dispute

This case involved a judicial review application by the Canadian Broadcasting Corporation (CBC) seeking to overturn a decision made by labour arbitrator Vincent Ready. The respondent, Canadian Media Guild (CMG), is the union representing the grievor, Jennifer Van Evra, a CBC employee whose employment ended following a dispute regarding accommodation of medical restrictions on her work schedule. After her departure, a disagreement arose regarding the amount of separation allowance owed to her under the collective agreement. The key issues were how to calculate her continuous service and whether periods of part-time work or unpaid leave should reduce the allowance. The dispute was submitted to arbitration by agreement and resolved based on written submissions.

The arbitrator’s findings

In his January 2025 decision, Arbitrator Ready ruled in favour of CMG. He determined that the grievor’s continuous service should be calculated from September 23, 2002, when she began working for CBC as a temporary employee, rather than October 24, 2005, when she became a permanent employee. He also found that most of the grievor’s absences were due to CBC’s failure to accommodate her disability or to provide sick leave, and therefore should not be deducted. The arbitrator further rejected CBC’s argument that it had a long-standing practice of prorating separation allowances for part-time service. He found no convincing evidence that CMG had been aware of or had acquiesced to such a practice. As a result, the grievor was awarded a separation allowance of $96,782.

CBC’s grounds for judicial review

CBC argued that the arbitrator’s decision was unreasonable and procedurally unfair. It asserted that the arbitrator had failed to explain why he adopted the earlier start date or declined to prorate part-time service. CBC also claimed it was denied procedural fairness because it was not allowed to call viva voce evidence to support its arguments, particularly concerning past practices. It submitted an affidavit on judicial review from a human resources advisor asserting that pro-rating had long been the CBC’s practice. The union moved to strike parts of this affidavit, arguing it was inadmissible on judicial review.

Court’s analysis and deference to the arbitrator

Justice Nakatsuru, writing for the Divisional Court, dismissed the application. The court applied the reasonableness standard set out in Vavilov and emphasized the deference owed to labour arbitrators in interpreting collective agreements. The court found the arbitrator’s decision was grounded in a logical interpretation of the agreement, with both parties having presented comprehensive written submissions. Although the arbitrator’s reasons were brief, they were appropriate in the context of a mutually agreed written proceeding. The court also ruled that the affidavit evidence submitted on judicial review did not meet the threshold for admissibility and, even if admitted, lacked probative value on the question of union awareness.

On the issue of procedural fairness, the court found that CBC had not made a meaningful effort during arbitration to indicate it intended to call oral evidence. It merely reserved the right to do so in general terms and waited until judicial review to present the evidence. The arbitrator was not required to reopen the proceedings based on such a reservation, and CBC had ample opportunity to respond in writing to CMG’s submissions.

Conclusion and result

The Divisional Court dismissed the application for judicial review, finding the arbitrator’s decision reasonable and the process fair. CBC was ordered to pay $11,000 in costs to CMG. The ruling reinforces the high level of deference granted to labour arbitrators and the need for parties to clearly raise evidentiary issues during arbitration, not after the fact. The court also confirmed that procedural fairness must be evaluated in light of the agreed process, especially where written submissions are the chosen method of adjudication.
