Where abouts is she in Canada? I know of one midwife in my area (near your area) who is not affiliated with the system. I can't say if she does VBACs or what limitations she puts on her practice, but if it interests you, I could give you her number.
Anyways, I'm just seeing this post now, it may be too late?
Also, Rivka, I was given your name when looking for a doula about 8 years ago! Small world But for whatever reason you were not available and I ended up with a student doula who got to witness my son being born at home by accident, and all was WELL
