Vista owned a shopping mall and leased space to Zellers, which operated a retail store.
Zellers notified Vista in February 2004 of its intention to cease operations in May 2004, although the lease did not terminate until April 2005.
Vista sued, claiming Zellers was obliged under "continuous use" clauses in the lease to operate until the lease ended.
The trial judge found that Zellers was entitled to close when it did, interpreting the continuous use obligation as qualified by the hours of operation clause.
The Court of Appeal reversed, holding that the continuous use obligation in sections 8.01 and 8.05 was not overridden by the hours of operation clause in section 8.01.1, and that Zellers breached its obligation by closing prematurely.
