Did Canada spy on journos at the Toronto G8/20 summit?

Ten days ago The Guardian published GCHQ briefing slides, courtesy of former NSA contractor turned whistleblower Edward Snowden, revealing :

Foreign politicians and officials who took part in two G20 summit meetings in London in 2009 had their computers monitored and their phone calls intercepted on the instructions of their British government hosts, according to documents seen by the Guardian. This included:
• Setting up internet cafes where they used an email interception programme and key-logging software to spy on delegates' use of computers;
• Penetrating the security on delegates' BlackBerrys to monitor their email messages and phone calls

The inclusion in the docs of the Communications Security Establishment Canada logo along side those of NSA and GCHQ, and the mention of bugged internet cafes and BlackBerrys, put me in mind of Canada's $2-million indoor fake lake built for the G8/20 the following year so that 3,000+ Canadian and foreign journos could, in Greg Weston's words at the time :

"file their reports ... their feet dangling in the water ... from only cottage dock in existence with bar service and high-speed Internet connections."

And according to Weston, they were all provided with free "special summit edition BlackBerrys" too.
