Fraser Valley
region of the Fraser River basin in southwestern British Columbia downstream of the Fraser Canyon
The Fraser Valley is a geographical region in southwestern British Columbia, Canada and northwestern Washington State. It starts just west of Hope in a narrow valley encompassing the Fraser River and ends at the Pacific Ocean stretching from the North Shore Mountains, opposite the city of Vancouver BC, to just south of Bellingham, Washington.
In casual usage it typically describes the Fraser River basin downstream of the Fraser Canyon. The term is sometimes used outside British Columbia to refer to the entire Fraser River sections including the Fraser Canyon and up from there to its headwaters, but in general British Columbian usage the term refers to the stretch of Lower Mainland west of the Coquihalla River mouth at the inland town of Hope, and includes all of the Canadian portion of the Fraser Lowland as well as the valleys and upland areas flanking it. It is divided into the Upper Fraser Valley and Lower Fraser Valley by the Vedder River mouth at the eastern foothills of Sumas Mountain, although the Lower Valley section upstream of McMillan Island and the Salmon River mouth (at Fort Langley) used to be called the Central Fraser Valley up until 1995 (see Central Fraser Valley Regional District).
Administratively, the Fraser Valley comprises parts of the regional districts of Metro Vancouver and the Fraser Valley Regional District. The main population centres in the Fraser Valley are Greater Vancouver, Abbotsford and Chilliwack.
History
This section of the Fraser River is known by local indigenous peoples as "Sto:lo" in the Halqemeylem language of the area, and this term has been adopted to refer to all of the indigenous peoples of the Fraser Lowland, other than the Squamish and Musqueam. The indigenous peoples of the area have long made use of the river valley for agricultural and commercial exploits and continue to do so today.
The Indigenous people were not consulted in the Treaty of Oregon, which saw the United States and Great Britain define and recognize each other's claims to the area.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Fraser Valley”, the useful work is to connect “region of the Fraser River basin in southwestern British Columbia downstream of the Fraser Canyon” to the records capable of establishing context and consequence.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q3554074. Authority coordinates are 49.108, -122.292. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1995.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
