The Ontario Superior Court in Dziedziejko v Canopy Growth held that materiality may be inferred from a significant share price drop following corrective disclosure, granting leave to pursue secondary market misrepresentation claims. The decision signals a potential shift from contextual materiality analysis and raises challenges for issuers with volatile share prices.

In Oliva v. Dickson (2025 ONSC 6666), the Ontario Superior Court confirmed that Building Code compliance can be an implied term of an Agreement of Purchase and Sale and a basis for vendor-builder liability in negligence. Even without structural failure or express contractual representations, failing to obtain required permits may breach both contractual and tort duties. The decision is a cautionary reminder that regulatory compliance defines both legal risk and commercial expectations in real estate transactions.

Canadian courts generally treat real estate deposits as forfeitable upon a purchaser&rsquo;s default, distinct from unenforceable penalty clauses. However, under the Redstone factors, courts may grant relief from forfeiture where a deposit is grossly disproportionate to the vendor&rsquo;s damages or where retaining it would be unconscionable in the circumstances.
