Elliot Lake and Serpent River First Nation will honour a new working agreement between them as part of National Indigenous Peoples Day.
The city is located within Serpent River First Nation traditional territory covered under the Robinson-Huron Treaty.
Both sides have agreed to work together on economic and land use development.
Serpent River First Nation Band and Council unanimously passed a motion on Monday.
Last week, Elliot Lake council unanimously endorsed a motion to SRFN council requesting a plan for a closer and equal working relationship between the neighbouring municipalities.
The two sides will come together at the Miner’s Monument at noon on Thursday to raise the First Nation flag as a first step in the new relationship.
