In general, you will have two years to start an action if your claim is after January 1, 2004. However, there may be shorter time limits for starting actions and certain defendants must have notice of your intention to start a lawsuit within days of the incident. If your case involves suing a municipality for failure to remove snow and ice, you must assume you have 10 days to give written notice. In the case of the province of Ontario, assume you have to give written notice within 10 days. As a result, you should consult a lawyer immediately following an incident to ensure that proper notice is provided.
