According to the CBC here, the federal government has told CSIS that it can use information that was possibly extracted under torture. The CBC reports:
The latest directive says in “exceptional circumstances” where there is a threat to human life or public safety, urgency may require CSIS to “share the most complete information available at the time with relevant authorities, including information based on intelligence provided by foreign agencies that may have been derived from the use of torture or mistreatment.”
In such rare circumstances, it may not always be possible to determine how a foreign agency obtained the information, and that ignoring such information solely because of its source would represent “an unacceptable risk to public safety.”
There has been criticism from opposition MPs and Amnesty International. The aforementioned CBC article quotes Jack Harris (NDP) in which he says, “You’re indirectly supporting torture, encouraging torture, by making a statement that you’re prepared to continue on an ongoing basis dealing with countries that use torture as a matter of course.” The debate seems to come down to whether you believe that exceptional security concerns justify the use of tainted intelligence or that doing so is supporting the use of torture.
