Алжирлік белімгер, Пакистан және Канададағы күмәнді байланыстар

In March 1990, the Algerian government stormed the house and arrested the FIS members within. Harkat was not present, and was warned by his uncle that security forces were seeking him.

Harkat departed in April 1990 for a trip to Saudi Arabia using a Hajj passport. For the next four years, Harkat worked and lived out of a Babbi warehouse. He picked up shipments of food and relief supplies for the refugee camps in the city from the Peshawar airport and train station, earning $300–500 monthly. CSIS has alleged that during this time he also worked for Human Concern International. They suggest that this meant he was a formal colleague of Ahmed Khadr, and that he may have run a guest house for foreign mujahideen traveling to participate in the Afghan civil war. In June 1994 Harkat lost his job. He lived off his $18,000 in savings for the next year. CSIS contends that Pacha Wazir, to whom they believe Harkat is referring, is an Emirati citizen known to have connections to al Qaeda. The Canadian Security Intelligence Service (CSIS) alleges that Harkat and "Mohammad Adnani" were the same person, and that during this time, he joined the more militant Groupe Islamique Armé wing of FIS. They allege he eventually aligned with Gama`at Islamiyya. CSIS will not provide a source for this claim, arguing that the information came from "open sources". In Kuala Lampur, he purchased a forged Saudi passport in the name of Mohammed M. Mohammed S. Al Qahtani for $1200 from a stranger named Abu Abdallah Pakistani, to carry in addition to his legitimate Algerian passport. Saudi passports did not require entry visas to visit Canada.

Holding about $1000, Harkat flew from Malaysia to Toronto via the United Kingdom on October 6, 1995. Harkat said that he would be persecuted by the Algerian government if he returned, due to his past membership in the FIS. His claim was accepted on February 24, 1997. They never met again after the 5 hour drive. Harkat was also in contact with Fahad al Shehri, who was later deported from the country. In 2004, he recanted his denial and admitted using the name in Pakistan. He became addicted to gambling, and lost several thousand dollars prompting authorities to ask where he'd gotten the money in the first place. He said that a man named Wael, a mutual friend with Harkat's close friend Abdel Mokhtar, had come to Canada with $60,000 to start a business. Liking Harkat, he offered to loan him $10,000 and then an additional $8,000 to open an antique store and a gas station. Harkat also stated that the money was from Mokhtar, rather than Wael. It later came to light that one of the CSIS agents detailed to collect information on Harkat had been Theresa Sullivan, who had been fired in 2002 after she carried on an extramarital affair with one of her informants. Given this behavior, Harkat questioned in court whether information she provided about him to CSIS was reliable. Public statements indicated that Abu Zubaydah, who was waterboarded during harsh interrogations by the United States, described a man "similar to" Harkat running a guest house in Pakistan that shuttled mujahideen to Chechnya, although he did not use Harkat's name. On March 22, 2005, Federal Court judge Eleanor Dawson ruled that the security certificate binding Harkat was reasonable. In April 2006, he was moved, along with the other four detainees, to a section at the Millhaven Institution specifically built for those held under security certificates.

On May 23, 2006, Harkat was released on a $100,000 bail by Justice Dawson. Additionally, Harkat was required to wear a tracking bracelet and was prohibited from using electronic means of communication. Any trips outside of his house were to be approved by the Canada Border Services Agency (CBSA) 48 hours in advance. The CBSA were also allowed constant access to his house, were required to approve any visitors to the house, and had two agents accompany him on any outings. On June 13–14, 2006, the Supreme Court of Canada heard the case of Harkat v. Canada on the constitutionality of security certificates. On December 22, Harkat's lawyer, Paul Copeland, announced that Federal Court Chief Justice Allan Lutfy would grant a judicial review of the original deportation order in Federal Court. The Canada Border Services Agency added six full time positions for surveillance agents to follow Harkat at all times, at an annual cost of $868,700, as well as purchasing a new $31,000 car for the tailing, and spent $5,000 monthly to have staff monitoring Harkat's tracking bracelet. On January 29, 2008, CBSA agents entered Harkat's home while he was showering, and placed him under arrest. They cited a breach of bail conditions, since his mother in law had not stayed at the house for several days following an argument with her husband. He was released after being questioned about the matter. On September 24, 2008, judge Simon Noël ruled that CSIS must disclose their "secret" evidence against Harkat, allowing him and his lawyers to view the material. CSIS said this could take up to six months. In May 2009, judge Noël had said that the unwillingness of CSIS to share its material regarding the reliability of an informant who gave evidence against Harkat was "troubling." He ordered them to disclose the confidential files to Harkat's defence lawyers who held security clearance. CSIS claimed to have destroyed all original copies of their evidence, and offered copies to the court and defence lawyers. While this theoretically cleared the way for his deportation to Algeria, the risk that he could be tortured if returned requires the Canada Border Services Agency to balance these risks prior to removing him from Canada. In March 2016 filmmaker Alexandre Trudeau, the younger brother of Prime Minister
Justin Trudeau, wrote a letter to Public Safety Minister Ralph Goodale asking that Harkat be allowed to stay, causing Erin O'Toole, the Conservative public safety critic and Democracy Watch to demand the Prime Minister recuse himself from any decision regarding Harkat.

The decision on the reasonableness of Harkat's security certificate became final when it was upheld by the Supreme Court of Canada in 2014. That said, his removal process remains outstanding. The next step in the process is what is referred to as the danger opinion stage. CBSA sought a danger opinion from the Minister of Public Safety and Emergency Preparedness to determine whether Mr. Harkat poses a danger to national security, whether the nature and severity of the acts committed reach a serious level of gravity, and, if so, whether the risk to Mr. Harkat in deporting him outweighs the danger posed to national security. The danger opinion package with Mr. Harkat’s submissions was provided to Immigration, Refugees and Citizenship Canada for decision on March 8, 2017, and a senior officer was assigned to consider the case on March 31, 2017. A decision was then reached in his case on October 2, 2018 in which the Minister’s delegate determined that Mr. Harkat should not be allowed to remain in Canada based on the nature and severity of the acts he committed. Harkat's lawyer, Barbara Jackman, told Al Jazeera she filed for a judicial review of his deportation order in November 2018. She stated that as of December 2019 the Federal Court has not received all the information on which the government based its removal decision, and without the complete record, it is unclear when the case would proceed. Jackman applied to court seeking an enhanced hourly fee and the payment of experts’ fees, an application which was denied in June 2020 on the basis that Mr. Harkat had not appealed his denial of legal aid and had provided insufficient information to the court about his finances. As of 2023, Harkat continued to litigate the terms of his release and monitoring conditions. The Federal Court was continuing to order that Bell Mobility provide records of Mr. Harkat's telephone calls and SMS text messages to CBSA. The substantive judicial review of his deportation order was also proceeding, with the Special Advocate for Mr. Harkat, who is entitled to review confidential information, having filed written submissions in the case with the court on March 9, 2023.
