ISO BS Born May 23, 1971 in MB

I am in search of my birth sister that I have just recently learned that I have. All I know is that she was born in Grace Hospital in Winnipeg, Manitoba. Her birthday I believe is May 23, 1971 and her name at birth was Heather May Anderson. The birthmother's name would have been Rosemary Anderson and I believe that the birthfather's name was Carl Anderson. I would desperately love to be able to find out any information on where she is and hopefully one day be in contact with her as I went for 33 years thinking that I was an only child to recently find out that I have a birth sister out there somewhere would be a dream come true to find her. If anyone has any information that would help me that would be greatly appreciated.
