The Canadian immigration system seeks firstly to bar criminals or terrorists entry. If these proclivities come to light after the fact, those tasked with enforcement seek to excise these individuals from our society. While they have formidable powers sometimes removal is stymied by the refusal, reluctance or intransigence of the country of origin or country of return.
Canada sought to deport rather than try him for terrorism or other crimes in a criminal court. Had he obtained Canadian Citizenship, he would not be subject to the jurisdiction of the IRPA and the Immigration and Refugee Board. The standard of proof to strip a Permanent Resident of status under the IRPA is far lower than that of "beyond a reasonable doubt". He was found inadmissible by the Immigration Division under s.34 based on evidence that he was plotting to bomb the US Consulate and the financial district in Toronto. The decision is chilling, detailing Malik's commitment to his cause, his dedication to wreak destruction and seek the death of innocent Canadians.
Malik and his lawyer didn't challenge the Minister's efforts; perhaps they knew it was a lost cause given the low threshold or bar that had to be met and the overwhelming evidence that established him to be a risk or threat to national security. I don't know whether it was smarter to get rid of Malik via immigration rather than going through the criminal process. If Malik was found not guilty, they could still act against him using s.34 and remove him; if he was found guilty, then a convicted terrorist with murderous intent would be secure behind bars for many years and then removed to Pakistan. The end result here is that Malik, still in his 30's, presumably with greater grievance against the West, will be released into a country with lax security and where ethno-religious violence and targeting of religious minorities occurs largely with impunity.
Malik was ordered detained after the finding of inadmissibility and the issuance of the removal order. He was probably looking forward to freedom in Pakistan and was probably frustrated himself when his removal was delayed for months. Obviously Pakistan was not thrilled to receive their wayward son back, and luckily they did. As far as the Pakistan High Commission was aware, Malik was not detained upon arrival. I hope this decision to safeguard our citizens will not risk the lives of innocents somewhere else.
