Whats your recent experience of turn around time s for Canadian passport renewal

Just like it says, my passport is full, larely due to the fact I need a stamp every 2 months.

If you have renewed your can passport, what was the turn around in real days?

My quandry is this -- I obviously need to renew, but with an immigration visit for a 2 month extension, followed up by an under consideration stamp around 2 weeks later, that leaves me around 40 days or so to renew the passport.

Canada consuate website says 20 business days which is uncomfortably clos to a potential month to renew. Any delays and im sunk.
