Opening arguments have been laid out in the court case regarding a stretch of shoreline property along Rainy Lake, known as the two-chain shore allowance.
Four area bands are seeking a declaration that the land was initially intended to be part of a reserve more than 125 years ago.
Lawyers representing the bands, the province, Canada, the town, and residents living in the area, also introduced several pages of documents to be used as evidence in Tuesday's opening.
The testimony in the hearing is expected to continue until late March.
