Yes my life was saved by one, absolutely go for it. That is why I became a chiropractor because one absolutely saved my life. I don't know Canadian practitioners, but the website sounds reasonable. Referrals from health food stores, and other people who know good ones is a great idea.
Before I started with my chiropractor, I had totaled a car (or someone totaled my car more accurately) the symptoms were mostly extreme nervousness at first, then pain in my neck. I started having signs that seemed like a stroke. My right side was messed up. I had feelings of drops of water on me that were not there, even and most disturbingly, in my eye. I waited way too long. But, that chiropractor saved me. By all means give it a try, IMO
