It's not well acceptable in Canada to have abortion. Most people believe it's against the will of God. Although it's legal for doctors helping doing it before fertilised egg grows into embryo, which i believe needs at least, say, 7 weeks, they are called murders. So I suppose the first doctor you called did not want to help you at all. That's why they asked you to wait until it's too late. And the second is so cautious that they did not want to be hooked up when you told them you had called a clinic already.
You may call the 3rd and just let them know your need and if they ask why, give then 1, 2 and 3 reasons justifying and, moral.
