Thornhill is an unincorporated community in northwestern British Columbia, with a population of 3,932 residents as of the 2021 Canadian census. It is governed by the Regional District of Kitimat-Stikine, and is classified as Electoral Area E. Thornhill is located immediately to the east of Terrace across the Skeena River. Thornhill is connected to Terrace by the Old Skeena Bridge and the Dudley Little Bridge.

History Thornhill, British Columbia, is named after Tom Thornhill, an English settler, and his wife Eliza, a member of the Kitselas First Nation. The Thornhills settled on the banks of the Skeena River in the late 19th century. Tom was a captain of a paddle-wheeler that operated along the Skeena River, while Eliza contributed to the community through trapping and hunting. Their cabin, built near the river, became the first permanent European settlements in the area. Eliza Thornhill died in 1907, and Tom Thornhill died in 1910.

The community grew with the arrival of settlers and the construction of infrastructure, such as roads and bridges, in the early 20th century. The development of the Grand Trunk Pacific Railway and the Canadian National Railway played a key role in the expansion of the region. As Thornhill developed, logging and sawmilling became important industries in the area.

During the 1970s, Thornhill saw growth due to as many people sought affordable housing in the community. The expansion of logging and other resource industries in the region also contributed to Thornhill’s population growth.

In the 1990s, the possibility of Thornhill’s incorporation was explored. In 1995, a study was commissioned by the provincial government to consider both the incorporation of Thornhill and the potential merging of Thornhill with Terrace. The study projected significant tax increases if Thornhill became independent, and in 1997, a referendum on the merger of Thornhill and Terrace was held. Thornhill residents voted against the proposal, while Terrace residents supported it.

Since then, discussions about the community’s governance have continued, with some residents advocating for Thornhill to become an incorporated municipality. In 2014, the issue of governance resurfaced with renewed calls for incorporation due to Thornhill’s relatively large population and unique governance, and the challenges of managing services within the regional district. Thornhill is considered one of the largest unincorporated communities by population in the province.

The community remains part of Electoral Area E in the Kitimat-Stikine Regional District, and as of 2024, efforts continue to explore the feasibility of Thornhill’s incorporation or other governance options.

Geography Thornhill is located within the Coastal Western Hemlock Wet Submaritime Biogeoclimatic Zone, characterized by dense forests consisting of Western Red Cedar, Western Hemlock, Balsam, and Sitka Spruce. The community is situated on the southwest side of the Skeena River, with several tributaries including Thornhill Creek, Hurley Creek, and Kofoed Creek, which are fish-bearing streams. The Skeena River is a central natural feature in the area, supporting salmon and steelhead populations.

Notable topographical features in Thornhill include Copper Mountain to its west and Thornhill Mountain. The land in Thornhill is primarily forested, with areas of steep slopes leading to the river. In 1979, it was estimated that approximately 45% of Thornhill’s land area is classified as either “not developable” or “restricted developable” due to natural and man-made constraints, including steep escarpments, drainage courses, and transportation networks.

The 200-year floodplain of the Skeena River extends to areas on the west side of Queensway Drive and west of Kofoed Drive. Development in these areas is subject to flood risk considerations, and mitigation measures may be required, such as elevating habitable spaces above floodplain levels.

There are also areas with steep slopes in Thornhill, particularly around Copper Mountain, and the escarpments that separate the Bench area from Queensway Drive and the Upper Bench from the Horseshoe. Development in these areas is generally restricted due to the risk of landslides.

Thornhill contains pockets of glaciomarine soils, which are fine-grained soils susceptible to landslides if disturbed.

Climate Thornhill experiences a temperate climate with mild temperatures and significant precipitation. The area receives approximately of precipitation annually, supporting lush vegetation typical of the Coastal Western Hemlock Wet Submaritime Biogeoclimatic Zone. This climate contributes to the dense forests in the region and influences local hydrological patterns.

Climate normals are from Northwest Regional Airport Terrace-Kitimat, about southwest.

Climate change may impact the community by contributing to increased flooding in local creeks and rivers, potentially affecting the landscape and infrastructure. Rising temperatures could also lead to higher river and stream temperatures, which may impact local aquatic ecosystems.
