The federal New Democrats are calling for a group of independent experts to investigate warrantless data collection by the federal government.
The Official Opposition says it also wants the group to recommend ways to ensure the privacy of Canadians is protected in the digital era.
NDP ethics critic Charlie Angus and justice critic Françoise Boivin said they were relieved when a previous bill, C-30, was withdrawn, but the government has simply resurrected the same measures in a new cybercrime bill.
In 2012, then-public safety minister Vic Toews told an opposition MP that he could stand with the government "or with the child pornographers."
"It's like the ghost of Vic Toews is back," Angus said Monday.
Privacy watchdog groups raised their concerns about potential privacy breaches with bills now before Parliament.
They include Bill S-4, which would amend laws governing how businesses collect personal data, as well as the government's cybercrime bill, which Ontario privacy commissioner Ann Cavoukian said has "overreaching surveillance powers."
