I don't have any data on physicians in particular.
I once again want to come back to the publication Women in Canada, which provides information on women studying in
STEM, which is science, technology, engineering, and mathematics.
According to that report, there are differences between men and women in terms of what they study. It shows that an increasing number of women are choosing to pursue studies in science, technology, engineering and mathematics, or STEM. I assume that changes will occur over time.
I'm sorry, but I cannot answer the question about medical professions.
