About us

Founded in 2015, Weymok, Les Constructions Atikamekw and Tapiskwan Foresterie are partnerships with members of the Atikamekw communities of Manawan, Obedjiwan and Wemontaci respectively.

These companies promote resources (human, material and financial) within the  communities through the development of specialized and large-scale projects where First Nation labour is prioritized.

In addition, Les Constructions Atikamekw is particularly proud to collaborate with the Manawan Band Council as part of a consortium, which was created in a collaboration and partnership spirit, to rally Manawan entrepreneurs.
