Aphria Inc. v. Canada Life Assurance Company, et al. (41665)

The appellant, Aphria Inc. (“tenant”), entered into a ten-year lease for commercial office premises with the respondent landlords and successors (collectively, “landlord”). The tenant served a notice of repudiation on the landlord and vacated the premises. The landlord did not accept the tenant’s repudiation of the lease. Ultimately, the landlord sued the tenant for rents owing.The motion judge in the Ontario Superior Court of Justice granted the landlord summary judgment for the rent owing plus interest. The motion judge declined to grant the landlord judgment for future rent. The motion judge dismissed the tenant’s cross-motion for summary judgment for a declaration that if rent was owing, the amount was capped at rent owing for two years from the date of default pursuant to the lease. The Ontario Court of Appeal unanimously dismissed the tenant’s appeal. It held that the motion judge did not err by refusing to depart from Highway Properties Ltd. v. Kelly, Douglas and Co. Ltd., [1971] S.C.R. 562, in order to recognize a duty to mitigate on commercial landlords who reject a repudiation of a lease by the tenant. The court also held that the motion judge did not err in his interpretation of the lease.
