Is it permissible for a woman to practice medicine in Canada, where there are no separate facilities for women in hospitals, or is it better for her to remain at home?

It is not permissible for a woman to work in a mixed environment due to the corruption that results from it. However, if she can avoid the forbidden mixing with men by having a private place for herself, then there is no objection. It is permissible for her to work as a doctor in a private clinic or a hospital where there is no mixing, or in an Islamic center where she treats Muslim women. Otherwise, let her fear Allah and devote herself to her obedience, worship, raising her children, and staying in her home. For whoever fears Allah, He will provide for them from where they do not expect.
