Limitation does not run against tortfeasor who caused damages while tortfeasor is trying to fix problem

Presidential MSH Corporation v. Marr Foster & Co. LLP, 2017 ONCA 325:

[20]        First, the cases suggest that a legal proceeding against an expert professional may not be appropriate if the claim arose out of the professional's alleged wrongdoing but may be resolved by the professional himself or herself without recourse to the courts, rendering the proceeding unnecessary.
