The current chief of the Long Plain First Nation is David Meeches, who was elected in December 2023, returning to the post after his tenure ended in 2013.

The reserve is home to various amenities, including Arrowhead Grocery, a grocery store opened in 2016; Arrowhead Internet Services, a wireless internet service provider that provides broadband connectivity to underserved markets; and Crossing Gas Bar.

[9] In 2000, the Long Plain First Nation Council entered into a 50-year head lease (now extended to 75 years) with Arrowhead Development Corp.

[9] Today, the lands are subleased to the Keeshkeemaquah Conference and Gaming Centre, Miskwaanakwadook Office Building (opened in 2006), Arrowhead Gas Bar, Rufus Prince Building, White Cross Drugs and Walk-in Clinic, and Long Plain Housing Authority.

[12] In 2011, a significant portion of the 2,600 m2 (28,000 sq ft) building that existed there on 480 Madison was renovated and leased to the Yellowquill College Inc.; the remaining space was renovated in 2012 for office space and was leased to Aboriginal Peoples Television Network (APTN), Manito Ahbee, Eagle Vision, and Treaty Relations Commission of Manitoba.

The 480 Madison building continues to house Yellowquill College, Manito Ahbee, Eagle Vision, and the Treaty Relations Commission, as well as being home to the Manitoba First Nations Education Resource Council, Saint Elizabeth First Nations Inuit and Métis Program, Setoskatowin, and the Assembly of Manitoba Chiefs.
