NOT TRUE.
Canadian citizens DO NOT need a visa to VISIT the USA,.
THEY DO need a visa to WORK or go to SCHOOL ....in the USA.
In this case the woman and two friends were going to a spa in Vermont ,for the day.
The CBP officer was WRONG when he said that she needs a Visa . She does not.
The US Consulate in Montreal confirmed that fact, yesterday.
For those that don't get it...Here is a link to the US Department of State's web sight about what Canadians NEED to enter the US.
READ the first paragraph, which clearly states " Canadians do not need a visa to enter the US unless they intend to live and work here, or attend school here ".
