Can a plaintiff amend the statement of claim to assert constructive dismissal damages?

By contrast, a proposed amendment will not be permitted where it advances a “fundamentally different claim” after the expiry of a limitation period: Frohlick v. Pinkerton Canada Ltd. In that case, the court did not permit the plaintiff in a wrongful dismissal action to amend the statement of claim to assert a claim for damages for constructive dismissal on the basis that the limitation period had expired. This court dismissed the appeal. The amendment regarding constructive dismissal related to events that occurred prior to the events described in the original statement of claim that were unrelated to that claim. The defendant was unaware of the new allegations prior to the plaintiff seeking the amendments, and the events were not put in issue or encompassed within the original claim.
