The appellant was unlawfully dismissed for union activities on the same day her employer sold its undertaking to the respondent.
The investigation commissioner ordered the respondent, as the new owner, to reinstate the appellant with compensation pursuant to section 36 of the Labour Code.
The Superior Court upheld this decision, but the Court of Appeal reversed it.
The Supreme Court of Canada allowed the appeal, holding that a complaint for unlawful dismissal and the resulting reinstatement order are proceedings relating to the securing of a collective agreement, and therefore section 36 applies to bind the subsequent purchaser.
