other parties lawyer disclosed private health info

I was directed if i wrote the Master of the court that the other lawyers in the case has to receive all copies of correspondence also. The court had directed me if i give my personal health infor in an affidavit then it would be a public record. So i wrote to the master and C.C. to the other sides lawyers. This one lawyer passed that private info, as it was said gave that letter to his client and his client went on the internet and made nasty comments about my health issues, making fun of them and making rude comments to me about my home town and my doctors on the internet. That lawyer when i complained to the master and him, paid me no notice. I asked him if this is how he handles all the private info of the court, just passes it on to people who's business is not without my concent to do so even. What can i do about this lawyer, he has been very smug and not very helpful in th course of this case. I am representing myself and anything i ask him he wont tell me just tells me to show up in court. What is my recourse here. does anyone know. this is in canada not usa. Lavisa
