BlackBerry has been losing market share in recent years to both Apple and the Android operating system, used in Samsung and HTC devices, among others. And the first round of Blackberry 10 phones, the Z10 and Q10, have struggled against the latest iPhone and Android devices.
The company recently launched the BlackBerry Q5 in Canada. The Q5 runs the company's new operating system, a follow-up to the original Q10 keyboard model and the Z10 touch-screen model that were introduced earlier this year.
