This is what was sent to our email from the agent, I'm sure its a quick copy and paste method they use and don't actually type out the email word for word.
Sir, Madam,
Thank you for contacting Citizenship and Immigration Canada. I am pleased to follow up on your request:
Open Work Permit – Sponsorship of a Spouse or Common-Law Partner in Canada
If a spouse or common-law partner is sponsored from inside Canada, they can apply for an open work permit by completing an Application to Change Conditions or Extend Your Stay in Canada as a Worker (IMM 5553). This application must be sent before their status expires in the same envelope as the sponsorship application. This will allow them to keep a legal status in Canada up until the time their application for permanent residence is *approved in principle.
If their status expires before the application for permanent residence is approved in principle, they will still have a legal status in Canada. This is called implied status. Please note that the open work permit will only be issued once the application for permanent residence is approved in principle. Visit our Web site to see how long it may take to get approval in principle.
If the sponsored person did not send an open work permit application with their permanent residence application, they can send it, by mail, at any time while it is in process by writing Open Work Permit - Application for permanent residence in Canada - Spouse or common-law partner on the top of the form. They should also include proof that the permanent residence application was submitted. The open work permit application cannot be submitted online.
