The Toronto Police have completed the installation of 77 new video surveillance cameras in the G20 Summit security zone to supplement their 18 existing ones, says a Canadian Press report.
 
"These additional cameras will support the G20 security measures and will be monitored during the course of the event," police said in a news release. "The additional CCTV security cameras will be removed at the completion of the G20 Summit."
 
The summit occurs June 26-27 and involves the leaders of the world's 20 largest economies and their entourages.
 
The estimated cost was $179 million, but the project ultimately cost $1.1 billion, the report says.
