My friend got into a car accident (she was at-fault). If she was not served with a lawsuit within the statute of limitation (a 2 year period for Ontario, Canada), is she still able to be sued? Note that the lawsuit was filed within the statues of limitation (within the last week of it expiring), but she was unaware that it was commenced by the plaintiff until after the 2 year period.
Note that she was not yet served the papers, but she is now aware (from sources other than the plantiff) that they are trying to contact her to serve her. How long do they have to serve her before the lawsuit expires?

It doesn’t matter when she was served. As long as it was filed within the 2 year window then that is all the Court cares about. It’s the filing date that matters.
