I have received my Bridging Open Work Permit on 30/October/2018. I have received my email close to midnight from my lawyer.
For people wondering what to expect, It is a very simple letter that states, Date, your UCI, Your application number that starts with "W" and your name, adress. Then you get this paragraph:
Lastly the document states the type of visa, validity dates and the document number.
" Your application to remain in Canada as a temporary resident has been approved. A secure document has been mailed to you at the address that you provided when you made your application. If you have not received your secure document within six weeks, contact IRCC. "
Hope this helps to people who are waiting for it
