Did you submit an Inland application? If so, there is a Public Policy for those that are out of status as long as the applicant is NOT deemed to be removal ready
before submitting the application.
IMHO, you should confer with a qualified immigration lawyer ASAP.
Not sure if this is helpful, or even applies in your situation, but...

Exclusion orders
An exclusion order prohibits a person from returning to Canada for one year without written permission or five years if issued for misrepresentation.
Deportation orders
A deportation order permanently bars a person from returning to Canada unless permission to return is obtained from the Minister of Immigration, Refugees and Citizenship Canada.
Q3. What recourse mechanisms are available?
There are a number of mechanisms available. Persons who are deemed to be inadmissible to Canada can, in certain circumstances, seek re-dress at the Immigration Appeal Division. An individual may file an application for leave and judicial review before the Federal Court against any decision made under the Immigration and Refugee Protection Act.
In certain instances, these applications can result in an automatic stay of removal until a decision is rendered by the courts. In instances where the application does not trigger an automatic stay, the individual may ask the Federal Court to grant a stay of removal pending the judicial review. If the court grants the request and stays the removal, the CBSA must comply with the Court order and not remove the individual until the case has been resolved.
