But John Duncan, minister of Aboriginal Affairs and Northern Development, told Makivik in a letter that the review now underway in Nunavut is adequate.
"In conducting its review, the Nunavut Impact Review Board has sought evidence on and will consider information provided in respect to potential transboundary impacts in adjacent jurisdictions due to the project's shipping activity in the scope of its assessment," the letter stated.
Makivik representatives participated in the final hearings into the Mary River project last month. They told the Nunavut Impact Review Board the project could affect Nunavik waters and wildlife.
"We are disappointed considering the scale of the shipping that's going to be going through the Nunavik marine region" said Jobie Tukkiapik, president of the Makivik Corporation.
"I know they say they won't use that region but, with all the ice conditions that do happen and all the noise it's going to create throughout the year, we are disappointed."
Makivik is concerned about the proposed year-round use of icebreakers, and the possibility of a fuel spill.
Tukkiapik said the Makivik board will discuss Duncan's letter further and decide what to do.
A final decision on the Mary River project from the Nunavut Impact Review Board is expected next month.
