Canada rejected Wednesday US security concerns over its fast-tracked resettlement of thousands of Syrian refugees, as the Senate in Washington prepares to hold a hearing on the repercussions for America, AFP reports.

"We have put in place layers of security activity to ensure that our refugee initiative with respect to Syria can be successful," Canadian public safety minister Ralph Goodale told parliament.

"The program is working well and indeed it will resolve in something that Canadians can be very, very proud of," he added in response to questions about why the Ottawa government declined an invitation to appear before the US Senate hearing.
