Maybe the recent postal strike delayed this update, but I'm happy to say that Canada Post has updated their app today. This update, v3.1, brings a major UI overhaul & brings an important new feature: Postal Code Search.
If you've never used Canada Post Mobile App, you'll be happy to know that it has many features:
Use Picture Postage by taking a picture with your device, or access any photos that you have stored on your camera roll -- share life's precious moments, create your own stamp!
Use Track a Package to track and check the status of your items. You can give the item a name and save it in the app (e.g., Mom’s package), so you can easily keep track of it until it is delivered.
Use Find a Post Office to locate the nearest Canada Post retail outlets, based on your GPS coordinates or an address that you enter.
