Can I apply for permanent residence while studying for a doctorate in Canada?

You can apply. You can apply for experienced skilled immigrants from the second year of your Ph.D. in Canada, starting from 20 12.

Generally, the audit time is about 2 years, and the results can only be obtained when your doctor is about to graduate. Because the Immigration Bureau is afraid that many people will use this to get immigrants quickly, the results can only be obtained after your doctor graduates. If you give up your doctorate halfway, your immigration will eventually be rejected.

In addition, the international student office of every university in Canada will provide questions and help for such immigrants, because such immigrant schools also need to provide relevant proof of attendance, so you can go directly to your Canadian university for consultation.
