"The Canadian Armed Forces are aware of the hard situation that is requiring significant resources of Canada Border Services Agency, the Royal Canadian Mounted Police and other partners in the area of St-Bernard-de-Lacolle", the military said in a statement.
Nearly 100 troops will be used to set up the camp site, which will consist of "modular tent shelters with lighting and heating and may temporarily accomodate close to 500 people", Department of National Defence spokesperson Evan Koronewski told CTV Montreal in an email.

The soldiers will have no role in security matters and will not participate in law-enforcement tasks.

Numerous recent refugee claimants crossing into Quebec are Haitians who have been living in America for years but now face deportation.
