I was able to call cic and got the answer. See below:
Generally, Work Permits are job specific. If you want to apply for a work permit, you need:
a Labour Market Opinion (LMO) from Human Resources and Social Development Canada; and
a job offer from a specific employer.
In some cases, work permits are not job specific, so no job offer or LMO is needed. These types of permits are known as open work permits.
As an exception, you can apply for an open work permit if you:
have applied for permanent residence in Canada under the live-in caregiver class and your application has been *approved in principle;
or
are a **family member of the person listed above and you are included in their application for permanent residence.
To apply for a work permit:
1. You must send an Application to Change Conditions or Extend Your Stay in Canada as a Worker to the Case Processing Centre in Vegreville, Alberta.
2. You must include a copy of your letter of approval in principle.
3. Visit our Web site to see how long it may take to process your application.
To help avoid delays or a refusal, make sure that you:
properly complete and sign the application form(s);
include all the documents listed on the Document Checklist (IMM 5556);
make your payment either on our Web site a credit card or at a financial institution (e.g. a bank) with an official Receipt (IMM 5401). If you apply for more than one service on a single application, you have to add the cost for each service; and
include the proof of payment.
* Approved in principle means that you received a letter from the Case Processing Centre or the local office stating that you are eligible to apply for permanent resident status but that a final decision will not be made until all requirements for becoming a permanent resident have been met. These requirements include medical, security and background checks for you and, if applicable, your family members.
**A family member is a spouse, common-law partner, dependant child or dependant child of a dependant child.
