Not exactly on the same boat, but mine was received in Ottawa on April 17, and I was not able to check anything or see any changes until yesterday. Not quite sure if this will still work, but you might want to check with CIC call centre to see what's going on.
From what I heard, they should process the COPR within two weeks of receiving the passport, and they won't hold your passport more than a month.
Once they issue COPR, your MyCIC account status will change to Approved, and within few days your return tracking code should be activated.
