@Maybach20 , where about Ontario you live? Did the GP you currently see order an ultrasound and prenatal bloodwork yet?
Most midwifes would prioritize out of country low-risk pregnant women with no OHIP. Try to fill out as many as application forms you can. Perhaps try going to their clinics and talking to them in person. Unfortunately, you may need some luck too.
I hope you are accepted as a patient soon. It is very sad that many pregnant women with no ohip has to go through similar situation. My wife and I have been there and I know how you feel. All the best.
