The Canadian wireless industry generated $20.7 billion in direct GDP in 2011, Nordicity said in a new report commissioned by the Canadian Wireless Telecommunications Association (CWTA). In a study called “The Benefit of the Wireless Telecommunications Industry to the Canadian Economy,” released Monday, the CWTA said the Canadian wireless industry’s GDP contribution was up 15 per cent in 2011 from $18 billion in 2010, primarily due to the increasing use of smartphones and wireless data services. Canadian wireless network operators made $2.6 billion in capital investments in 2011, the report said, up slightly from $2.5 billion in 2010. The anticipated 700 MHz spectrum auction, scheduled for later this year, is also expected to bump those investments, the report said. It noted that capital investment in the industry spiked to $6 billion in 2008 after Industry Canada’s last wireless spectrum auction.
