Believe me when I say that I sympathize with how you're feeling. I also applied without status (way more than 90 days), so I know the angst that goes along with feeling like an inferior human being, for getting into such a mess. I also accepted full responsibility for my conscious decisions that put me in that position...while at the same time being grateful to Canada for offering a way out.
Since Feb 2005, a person could apply for Spousal Sponsorship without having legal status thanks to a Public policy that was established by CIC Minister Joe Volpe:

This is been used for many
Inland applicants to become a PR, but...apparently only a handful of Outland applicants (those IN Canada without status, that submitted an Outland application), have been as fortunate. This could simply be that the overwhelming majority of people without status listen to what, apparently, all experts suggest; to apply
Inland if you are out of status. No idea if this is a known secret among professionals that
know how CIC works, or if they just assume that people aren't smart enough to know that they
can submit an Outland application while they are IN Canada. The issue is how the lack of status impacts the Outland applicant.
In September of 2014, the Inland Guide was changed. One of the changes, was the section that had mentioned this Public policy, and confirming that legal status was NOT required to apply. That language was removed and replaced with "Legals status is required...blah, blah, blah...", yet many people have since (and are still) submitting Inland applications and are being approved.
The real reason for your concern, is the fact that you have submitted an Outland application. As canuck_in_uk mentioned in a separate thread, there has only been one person, recently, that was told to leave Canada because she was found to be in Canada without status, with an Outland application submitted. There is nothing to indicate wither way, how CIC/CBSA treat those applicants, compared to Inland applicants, that no longer have legal status.
All you can do is pray and be thankful that Canada is so generous when it comes to those without status. A person that has overstayed in The U.S. for more than 6 months, for example, could be banned from returning for 10 years, or more!
This too shall pass.
