The House of Commons passed the new anti-terrorism bill on April 24th 2013 and received royal assent on the 25th. The bill revived provisions from the Anti-terrorism Act passed just after the Sept. 11 attacks and adds some new ones that can very easily violate civil rights.
It is no secret that since 9/11 the increase in security and the sheer removal of civil rights and freedoms has been extensive. This of course comes under the guise of protection and safety, but still we fail to see any major terror attacks that have not been either 1. caused by the FBI themselves 2. have had government and other agency groups heavily involved or 3. have had a large number of factors suggesting the event was a staged attack. In fact, it was recently disclosed that of the 22 terror related attacks since 9/11, 14 of them have been created and caused by the FBI themselves. 
Some new provisions such as investigative hearings and preventive detentions have been added to the new act and are creating quite a controversial stir as many begin to question the real intention behind the passing of these bills. These came after an suspected terror plot was foiled where two men were allegedly plotting to derail a train in Toronto. Another shady accusation.
1. Investigative hearings are reinstated An individual can be forced to appear at a secret hearing without any charges being laid if authorities believe he or she has knowledge of a terrorist activity. The individual must appear and answer questions or risk being jailed for up to 12 months.
2. Preventive detentions are reinstatedAn individual can be held for up to three days on suspicion of being involved with terrorism. Upon release, he or she can be ordered to uphold probation-like conditions, such as not contacting certain people, for up to 12 months, without ever being charged with any offence.
