Sorry, but you need to understand the law before you quote it. The actual statute states: "Unless this Act provides otherwise, a proceeding shall not be commenced in respect of a claim after the second anniversary of the day on which the claim was discovered. 2002, c. 24, Sched. B, s. 4."
Limitations Act, 2002, S.O. 2002, c. 24, Sched. B
As soon as legal action is initiated the clock stops. Once a judgment is issued, they have 10 years to collect and can renew for another 10.
Your only recourse is to fight the judgment based on your not being served notice of the suit. But even if you win that, they will just serve you again and get a new judgment.
You are ALWAYS obligated to pay your contractual debts. Whether an SOL or a judgment expires, your obligation never expires until the debt is paid.
