Statute of Limitations (SOL) for Ontario:
Refer to the Limitations Act, 2002. It came into force on January 1, 2004.
There are a bunch of exceptions, but the main rule is as follows:
You have 2 years to bring a law suit once you discover a problem. So, if you stop paying me May 2004, I have until May 2006 to bring my law suit.
However, there is an ultimate limitation period of 15 years. The max time you have to bring any law suit is 15 years. Let’s say that in May 2008, your lawyer tells you that you could have sued your accountant for the bad work he did for you back in May 2004. While 4 yrs later, your 2 year limitation period start May 2008 – May 2010. But, by May 2019, 15 yrs later, you would have been out of luck.
Exceptions. Collateral has no limitations. If I loan you money in May 2004 to buy a house, and you secure it with the house as collateral. Then in April 2007, you stop paying me. Under the 2 yr rule, I only have until April 2009 to file suit, HOWEVER, since there is collateral involved, I can sue you whenever. I can sue you in April 2030.
There are other exceptions as well.
I hope I interpreted it correct.
