The former chief executive officer of BlackBerry added his voice to the chorus of people saying that Canada's main economic hurdle is keeping technology talent. From a report: "The biggest challenge as a country is retaining and recruiting the best people to build industries in Canada and not lose them to other jurisdictions," Mike Lazaridis, who left BlackBerry in 2013, said Thursday at the Waterloo Innovation Summit. Canada is pushing to become a technological leader as Prime Minister Justin Trudeau tries to shift away from a commodities-driven economy by increasing funding for technology and offering fast-track visas to highly skilled workers. Cities like Ottawa, the capital, have stepped up recruitment efforts targeting expats in the U.S., while Toronto and its surrounding cities submitted a regional bid Wednesday for Amazon.com's second headquarters. The BlackBerry inventor sees Canada as at the forefront of the development of quantum computers, technology that could transform the world by allowing computers to operate much faster and on larger data sets than ever before.
