The park is called Tursujuq and is located on the eastern arm of Hudson Bay.
The Quebec Government, the Kativik Regional Government and Aboriginal groups worked together to get the park made.
Maggie Emudluk, the chair of Kativik Regional Government, said work began on the park in the 1990s.
She said the biggest challenge was to include the Nastapoka River, as it was being looked at as a potential hydroelectric dam.
“But all the efforts, the determined efforts, have been heard, the voices have been heard and so now we can say today that the Nastapoka will be within the parks boundaries,” she said.
The park is 26 kilometres long and covers 6.5 million acres. The area includes a beluga estuary and land-locked salmon.
Emudluk said work still needs to be done to prepare for tourists, such as building access roads.
She said Inuit will still have fishing and harvesting rights within the park.
This is now the third park in Nunavik.
