Canada 's concerns about close border ties with US
By Jessica Murphy
BBC News, Toronto
The Canada-US border has become a fault line for Canadian fears surrounding the new US administration.
The uncertainty comes as Parliament considers a preclearance security bill that could give US border agents new powers and the Liberal government comes under pressure to reconsider an asylum pact with the US.
The US has made it clear secure borders are a top priority and while President Donald Trump has set his sights on Mexico and the Middle East, Canadians are still feeling a chill.
Pollster Nik Nanos, whose firm tracks Canadian attitudes towards the international boundary, said sentiment about the border is driven by two things - political rhetoric in the US and people's actual experiences at border crossings.
Both factors are driving anxiety as the new US administration begins to put its plans into practice.
