Quick solution??

i was thinking of going down to a POE to reinstate my status rather than waiting all the months to get it before sending off my PR/rehab applications.
- i messed up my initial extension of stay (just sent form, nothing else)

Me, my Canadian born wife and Canadian citizen-cert holding kids go down with all my papers etc.
The upside is I don't have to wait for my status, and when re-entering, they ask me about convictions - hear that they are both over 10 years (including driving ban), and deem me rehab'd

Could they issue a work permit there?

The downside is i dont get in and stuck in no-mans land on the Freedom Bridge and given just a 3 day visa to get a flight home

any suggestions?
