BlackBerry has been signalling for weeks that it would sell most of its Canadian offices in order to save some badly needed cash, and today it reached a deal to do just that. The pact will see the company sell over 3 million square feet of property in its homeland, leasing some of it back; the Waterloo headquarters should remain intact. Everything should wrap up before the end of BlackBerry's current quarter, which ends in May. The agreement should help BlackBerry focus on its core business (whatever that may be), although the move may not be enough when major customers like the White House are thinking of jumping ship.
