OTTAWA - Amnesty International is criticizing Canada for its refusal to arrest former U.S. president George W. Bush during a visit to British Columbia last year.

The human rights group says there was clear evidence that Bush was responsible for crimes under international law, including torture.

Amnesty had campaigned for Canada to arrest and prosecute him.

At the time of Bush's visit last October, the group maintained the former president authorized the use of torture against detainees at the Guantanamo Bay naval base, in Afghanistan and Iraq.

As a signatory to the United Nations Convention Against Torture, Amnesty says Canada has an obligation to take action against alleged violators, including Bush.

The report also chides Canada for its treatment of aboriginal people on a number of fronts, including its failure to adopt a national action plan to address high levels of violence facing native women.
