Boughton Law jointly represented 23 Alberta-based indigenous communities in their acquisition, for $1.1 billion, of an 11.57% equity interest in seven Enbridge-operated pipelines in the Athabasca region. This acquisition is the single largest indigenous energy transaction in North America. The pipeline assets are underpinned by long-term contracts and highly-predictable cash flows.
Athabasca Indigenous Investments Limited Partnership (Aii) is the special purpose partnership which, through a subsidiary, holds the 11.57% equity interest in the seven pipelines.
The indigenous communities which hold the equity of Aii are:
| Beaver Lake Cree Nation | Cold Lake First Nations | Frog Lake First Nation |
| Heart Lake First Nation | Kehewin Cree Nation | Onion Lake Cree Nation |
| Saddle Lake Cree Nation | Whitefish Lake First Nation (Goodfish) | Athabasca Chipewyan First Nation |
| Chipewyan Prairie First Nation | Fort McKay First Nation | Fort McMurray #468 First Nation |
| Mikisew Cree First Nation | Buffalo Lake Métis Settlement | Elizabeth Métis Settlement |
