My story about OWP application.
Mississauga received my OWP application along with PR one under common law partner in Canada class on Nov 03 2017. The GCMS note confirmed it. But I could not link this OWP app. Never. I called CIC call center almost every day during early January. ButI I was just advised that my OWP app was not entered in the system yet and still within the 4 months processing period. To secured my legal temporary resident status, I decided to re-send the exact same application to Vegreville on Jan 14 with an explanation as cover letter. Vegreville received it on Jan 18. And I could link this re-sent app on Jan 24. On early March, I called CIC call center again everyday around early March cause the 4-month period passed. Every time, the agent told me they would send a note to Mississauga office and what I could do is to wait. And No reply from Mississauga. Never. I thought my original application was just put aside somewhere alone in Mississauga office! And it did not returned to me!
On April 10, my second OWP app got approval.
If your situation is similar to mine, do re-send the app to Vegreville. Cause no one cares about you but YOURSELF!
