Sony Mobile has released the Android 5.1.1 Lollipop firmware update for the Xperia Z2 and Z3 series in Canada.

You can check below to see which firmware updates are available for which Canadian carrier.

The update has also landed on the Xperia Z2 and Z3 Tablet series for carriers in Japan and Taiwan.
