From September 2017 to May 2018, I traveled several times along the Canada-US border in the area of Roxham Road and Lacolle in Quebec, in search of traces of the passage of so-called illegal migrants. I retrieved objects, some of which probably belonged to migrants and others, possibly to border services officers (dog toys, gloves, etc ...) These are the objects that can be seen in this series of photographs. With photos of Canadian border landscapes taken in the winter of 2017 as background, I photographed those lost objects.
