Hi Muslima,
You may want to check out this
post. It's made up of many cysters from the Ottawa area that get together from time to time, they might be able to suggest a good doctor for you.
There is also this
Ottawa area doctor post with suggestions for area doctors.
Although
this post is quite long with recommended doctors from coast to coast, it can also be a good place start.
There are also websiteslike this
one where if you have the name of a doctor, you can read reviews. Just like anything on the internet though, make sure you take everything with a grain of salt.
Good luck finding a physician!
