You should talk with a personal injury lawyer in Ontario and see what he has to say. SOL's can be slippery and you really need your own lawyer to examine the: "when you should have know there was malpractice?" question.
Hire a lawyer if you where hurt. Put the electric company on notice of your condition. contact the attorney general and file a complaint about what happened. Ask the AG's office to put the utility on notice concerning your rights.
