The Islamic extremist who masterminded a terrorist plot to bomb Parliament and several buildings in the heart of downtown Toronto has become the first Canadian in history to have citizenship revoked under Bill C-24, a controversial Conservative measure passed last spring.

The new law gives the government the power to strip a dual citizen of their Canadian citizenship if he or she commits a serious crime.

At a campaign stop in Regina Saturday, Conservative candidate Jason Kenney confirmed that Zakaria Amara, a Jordanian-Canadian and member of the so-called Toronto 18, has been formally stripped of his Canadian citizenship.

鈥淗e expressed violent disloyalty for this country -- hatred for Canada -- and in so doing, through that conviction, he effectively renounced his own Canadian citizenship,鈥 Kenney said.

麻豆影视 has learned that the process has begun for at least three other convicted terrorists to have their Canadian citizenships revoked.

The decision to revoke Amara鈥檚 citizenship spurred criticism from rival politicians and Canadian law experts, with some suggesting the ruling is unconstitutional and sets a dangerous legal precedent.

Amara was sentenced to life in prison in 2010 with no chance of parole until 2016 for his role in plotting a series of terrorist attacks with the Toronto 18. The group wanted to draw Canadian troops out of Afghanistan.

Part of the group鈥檚 plan was to detonate bombs in U-Haul rental trucks in downtown Toronto, according to an agreed upon statement of facts from the case.

The Toronto 18 also harboured plans to attack nuclear power plants, RCMP headquarters and eventually target the Sears Tower in Chicago or the UN headquarters in New York City, according to court records.

Police thwarted the plot -- dubbed the 鈥淏attle of Toronto鈥 -- in a sweeping series of arrests in 2006. 

Deportation plan underway

Now that Amara's Canadian citizenship has been revoked, a plan has been set in motion to deport him to Jordan.

However, he will not be deported until his time has been served, the government confirmed. He is currently behind bars in a Quebec prison and is eligible for parole in 2016.

Deporting the convicted terrorist is a move that Amara鈥檚 lawyer denounced as 鈥渘ot in the best interest of Canada.鈥

鈥淚t鈥檚 counterproductive, it鈥檚 unsafe and it flies in the face of our entire prison system,鈥 Anser Farooq told 麻豆影视.

Setting a legal precedent

Amara likely won鈥檛 garner much pity over his lost citizenship, but Canadians should be alarmed by the law鈥檚 potential consequences, says Joel Sandaluk, an immigration and citizenship lawyer.

鈥淭he day that we sacrifice a lot of our legal values and legal precedents to fear, to demands for greater security, we lose track of who we are as Canadians, of who we are as a people,鈥 Sandaluk said. 鈥淎nd that鈥檚 an incredibly dangerous thing.鈥

Sandaluk acknowledged that Amara is precisely the type of criminal the law was written to target. But he said questions linger about who the law could affect in the future.

鈥淲hat about the next person, and the next person after that?鈥 he said.

鈥淥ne of the things we鈥檝e all seen over the years is that, a lot of times, anti-terrorism law can cause abuses -- people who weren鈥檛 necessarily intended to be caught in this kind of legislation can be caught. And the consequences are profoundly serious; they鈥檙e life-changing.鈥

He added the law is 鈥渄rafted broadly enough鈥 that it could create unintended consequences.

鈥淭errorism itself is not necessarily a clearly defined concept. And how this law may be changed or distorted over the coming years or decades is impossible to predict with any degree of certainty,鈥 he said.

Sandaluk suggested if Amara鈥檚 revocation is not challenged in court, one of the upcoming revocations likely will be.

鈥淭his piece of legislation is brand new and untested. How the courts handle it, to be perfectly honest, remains to be seen.鈥

Human rights lawyer David Matas said the decision is another instance of the Harper government drafting a law that is open to Charter challenges.

鈥淲e鈥檝e seen with this government a lot of Charter-vulnerable legislation, and they鈥檝e been losing Charter cases all the time. This might be one of those examples,鈥 Matas said.

NDP, Liberals pledge repeal

The landmark revocation comes about three weeks before Canadians head to the polls on Oct. 19. Opposition parties have challenged the premise of Bill C-24. Tom Mulcair says the NDP would repeal the law, and Liberal Leader Justin Trudeau reiterated Friday that his party would do the same.

鈥淯nder a Liberal government, there will be no two-tier citizenship,鈥 Trudeau said. 鈥淎 Canadian is a Canadian is a Canadian.鈥

NDP candidate Andrew Thomson accused the Conservatives of playing politics on the matter.

鈥淲hat we need to be careful of is that we are not stripping Canadian citizens of their rights simply because of the Conservatives鈥 interest in playing politics on this issue.鈥
