GUYS,
From what I've read on OPNP and CIC's website (links below) if you applied for nomination and have your certificate with you, you can use your nomination certificate along with a letter of support from OPNP to apply for a temporary work permit both before and after you apply for PR. According to the laws, only Ontario has this and it is meant to allow nominees who are going to lose status to remain in Canada legally and working too. So basically if you've been nominated but haven't applied for the PR yet you dont need to think about the Bridging work permit, there is another work permit called a Temporary work permit. Please give these links a read and tell me if you understand differently. I will be calling OPNP and CIC on Monday and two lawyers on Tuesday to obtain validation. Please read these websites and let me know what you understand too.
Since I''m not allowed to post the links ill describe what to type into google search:
Opportunities Ontario What's Next?
Operational Bulletin 406 - April 19, 2012
International Mobility Program: Canada–provincial or territorial agreements [R204(c)] (exemption code T13)
Also I'm reading about losing status and restoring it and it seems like you can apply for this work permit 90 days after yours expires as long as you stop working.
Search: "My work permit expired and I did not apply to extend it. Can I stay and keep working in Canada?"
