Apparently, there is no Lumia 925 on carrier Koodo in Canada and the reported device must have been unlocked and imported from some other region.
It seems Lumia Cyan has started rolling to North America region. A Lumia 925 owner on Canada’s Koodo network has posted some screenshots showing that his device has received Lumia Cyan update. Though the tracker page still shows the update as “under testing” for Lumia 925 on Koodo’s network. But, it may mean that Lumia Cyan will start rolling to Lumia devices in US / Canada soon. So, keep checking!!
In the meantime, you can read the Full Changelog of Lumia Cyan and Windows Phone 8.1 on our dedicated page.
