Canada and the United States are considering a new border security pact.
The plan is expected to involve joint border inspection agencies and greater intelligence sharing.
Canadian Prime Minister Stephen Harper is to discuss the proposal when he meets President Barack Obama at the White House on Friday.
CBC reported that Mr Harper and Mr Obama are expected to sign a framework agreement on security and announce a deadline of late 2011 for a deal.
But opposition parties in Canada fear the US will demand too much personal information about Canadian citizens and companies.
Meanwhile, the BBC reports that US Senators have reacted with concern to a new federal government report which found that only 32 miles of the 4000-mile border between US and Canada was adequately secured.
