Bell Mobility is apparently striving to reach the mobile carrier supremacy in Canada, as they have unofficially announced that they will be launching their LTE network before the end of 2011. This come merely days after Rogers made a similar announcement.

According to an internal document:
Bell has completed 4G LTE trials and we are currently deploying LTE as well. Our competitors will not get in front of Bell’s network leadership. We do not make announcements about our competitive network or product plans that are too far in advance of their actual availability to customers.
With Bell & Telus having deployed their 3G HSPA+ together in late 2009, I wouldn't be surprised if we will see the same with LTE deployment.
