A new study by the Toronto-based Mackenzie Institute says that 15 out of 80 international terrorist groups have members or supporters in Canada—and that the Canadian government continues to drag its feet on the problem.

Canada has allowed terrorists to move here, fund raise for their activities and violently repress others from their home countries who oppose them, according to a new study on terrorism. …

Among the groups are Sikh separatists like those accused of being responsible for the 1985 Air India bombing, violent supporters of the Sri Lankan Tamil Tigers and members of the Islamic extremist group al-Qaida, which perpetrated the terrorist attacks of Sept. 11, 2001, on the United States.

Written by institute executive director John Thompson, the report is due to be released July 12. An advance copy was obtained by The Vancouver Sun.

It says that many of the groups have potential for violence in this country, though most Canadians who have been killed so far have not been the victims of attacks against third parties.
