Just a pointer. Don't be too picky about choosing the best family doctor at this point. Just find out whoever is accepting new patients in your neighbourhood. Right now you need a family doctor just to get a referral to Ob-Gyn. You can always change your family doctor later. I could be wrong, but I don't think walk-in clinics can refer you to ob-gyn. This is what my family doctor told me.
Not sure about the specifics of BC, but here in Ontario, all Ob-Gyns are associated to the local hospital of your area.
Family doctor sends a referral request to the hospital and then the hospital arranges and schedules your visit to an Ob-Gyn.
Here in Ontario you don't get assigned a specific ob-gyn. The hospital basically maintains your file, and on each visit you get to see a new doctor.
I think the idea is to familiarize you with all doctors who are associated to the hospital since any of them might be on duty when the time comes.
My wife and I are expecting a baby very soon and this has been our experience so far with OHIP. It has been pretty well organized and hassle free so far. I am certain BC will be no different.
No other patients see a specific doctor but can be delivered by whatever MD is on call in the practice. An OB can't be on call 24/7. All depends on how your local OB practice works and how large the practice is. Each OB has privileges at a specific hospital so you can't choose what hospital you want to deliver at. Given that a large number of people don't have a family doctor, walk-in clinics must be able to refer to an OB. Definitely not their preference but if there are no other options...
