The ATR process is collaborative work, where First Nations work with Saskatchewan (provincial Crown) and Canada (federal Crown). The ATR process includes land selection, land acquisition, land management, ATR process, and reserve creation. In Saskatchewan, about 85% of First Nations use the Treaty Land Entitlement Framework Agreement ATR process; the remainder user the ATR Policy of the day. The ATR process is a time-consuming process and may become complicated by interests on the selection.
