These people can apply for a work permit without HRSDC approval but must still have a work permit to work legally.

A similar regulation exists for other people entering into Canada who require work permits which may be governed by other international agreements.
Some entrepreneurs, intra-company transferees and other workers who provide a significant benefit to Canada may not need to request a confirmation from HRSDC.
Foreign students doing co-op work. religious workers, reciprocal and exchange employment schemes do not require HRSDC approval.
Spouses and common-law partners of skilled foreign workers or spouses and common-law partners of foreign students doing post-graduation work in Canada do not need a confirmation from HRSDC.
Not requiring a confirmation from HRSDC does not mean the workers are exempt from requiring a work permit.
