The following paragraphs say it all.  If your study doesn't correct for same jobs, same career point, same area, it's meaningless.  If it's "all men that age in Canada vs. all women that age in Canada" it's nothing more useful than an observation:

"Several factors explain the pay differences. One is that women are more likely to work part time than men, in many cases because they take on child-care and elder-care responsibilities. They are also more likely to experience work interruptions in their careers.

Another reason is the types of jobs that people do. Jobs that are heavily female, such as cashiers and daycare workers, tend to be lower paid than many jobs that skew heavily male, such as truck drivers or construction workers."
