It is along with family sponsor for permanent residency. Visa just ran out
Ah - an inland spousal sponsorship application. That makes more sense.
You would have apply for a new open work permit (not an extension). The fees are $155 + $100.
If your IEC has already expired, that unfortunately means you are now in Canada without status (this is because the OWP application was returned). You'll need to resubmit the OWP with the corrected fees - however equally importantly, you'll also need to apply to restore your status (i.e. make your status in Canada legal again). You'll want to apply for restoration asap since the new OWP won't be approved until your status is restored.
Also recommend you move over to the Family Sponsorship section of the forum and post any further questions you have there.
