Canadian officials supplied Syrian torturers with interrogation questions for three Canadians who were detained and tortured in Syria and Egypt during the post-Sept. 11 crackdown on terror suspects. Documents obtained by the fifth estate show Canadian officials not only knew Abdullah Almalki, Ahmad Abou-Elmaati and Muayyed Nureddin would likely be tortured at the hands of Syrian intelligence officers, they supplied them with interrogation questions. Two separate federal inquiries found Canadian authorities played a role in the torture of Canadians abroad and the trio -- none of whom was ever arrested in Canada for suspected terror offences -- filed a $100-million lawsuit against the government in 2006. Earlier this year, their lawyers won a lengthy court battle with the RCMP and CSIS to gain access to nearly 18,000 pages of heavily redacted documents. CBC News obtained exclusive access to the documents. In “The Torture Files,” a joint investigation by the fifth estate and CBC’s The National, Terence McKenna explores just how far CSIS and the RCMP went in their collaboration with the brutal Syrian regime of Bashar al-Assad that resulted in the torture of three Canadians. The treasure trove consists of internal memos, briefing notes from field agents to their superiors, inter-agency communications, emails, reports and even a memo that shows at least one RCMP officer on the case might have had serious doubts about their targets. Watch Terence McKenna's report on The National on Monday, Tuesday and Wednesday, and Friday night at 11:30 PM on the fifth estate. The Torture Files also airs Sunday at 7 PM ET on CBC News Network.

Many ex-smokers say 'yes.' E-cigarettes are their salvation. Health Canada is on the cusp of deciding how e-cigarettes should be regulated.

In recent months, tens of thousands of desperate souls have been saved from certain death in the frigid waters of the Mediterranean.

They are images that shocked America and were shared around the world – disturbing cell phone videos taken by bystanders of police shooting black men in America. They became political fodder for an ugly presidential campaign. To capture what is really going on during these confrontations, police-worn body cameras are increasingly seen as the answer: a way to curb the killings - and police the police. But can the police-worn body cameras also distort the picture? Do they sometime give us an incomplete version of what really happened? Mark Kelley investigates what happens when police are “caught on camera” in the U.S. and Canada.

It was a tale all too common - a young Indigenous man drowned in Thunder Bay. Stacy DeBungee was last seen alive by some friends on the evening of October 18, 2015. What happened that night was a mystery, but three hours after finding the body the next morning Thunder Bay police issued a press release saying they found nothing suspicious about the death. It was the same rush to judgement they had been accused of in many other deaths of young Indigenous people. So the fifth estate went looking for answers and found several people who were there that night – but they had never been properly interviewed by the police. Gillian Findlay investigates.

On November 16, 1969, the body of a young woman was found along Mulholland Drive in Los Angeles. She had been stabbed 157 times. The body was never claimed.

Now the Los Angeles and Montreal police are trying to piece together the final weeks of Jurvetson’s life and the fifth estate helps uncover new clues that might help unlock a decades-old mystery.

A tale from the shadier side of the stock market - from the streets of Montreal, but with a cast of characters right out of a Hollywood movie.

Do these events point to a more fearful future? Do they suggest more dangerous and precarious times ahead for Muslims in North America?
