Yes, certain categories allow applying for a Canada Work Visa without a job offer. Open work permits do not require a job offer or LMIA and are commonly issued to spouses of work or study permit holders, international graduates eligible for post-graduation work permits, and some participants in international agreements. However, employer-specific work permits generally require a valid job offer supported by an LMIA. Eligibility for open work permits depends on meeting specific criteria set by the Canadian government.
