     MONTREAL (Reuters)-Crossing the US-Canada border (边界) to go to church on a Sunday cost a US

citizen $10,000 for breaking Washington's strict new security (安全) rules.

     The expensive trip to church was a surprise for Richard Albert, who lives right on the Canadian border.

Like the other half-dozen people of Township 15, crossing the border is a daily occurrence for Albert. The

nearby Quebec village of St. Pamphile is where they shop, eat and go to church.

     There are many such situations in these areas along the largely unguarded 5,530-mile border between

Canada and the US-which in some cases actually runs down the middle of streets or through buildings.

     As a result, Albert says he did not expect any problems three weeks ago when he returned home to the

US after attending church in Canada, as usual. The US customs (海关) station in this are is closed on

Sundays, so be just drove around the locked gate, as he had done every weekend since the gate appeared

last May, following a tightening of border security. Two days later. Albert was told to go to the customs

office, where an officer told him be had been caught on carnera crossing the border illegally (非法).

     Ottawa has given out special passes to some 300 US citizens in that area so they can enter the country

when Canadian customs stations are closed, but the US stopped a similar program last May. That forces the

people to a 200-mile detour along hilly roads to get home through another border checkpoint.

     Albert has requested that the customs office change their decisions on the fine, but he has not attended a

Sunday church since. "I feel like I'm living in a prison," he said.
