Fourth Line is a locality in Lambton, Ontario, Canada. It is classified as a village / hamlet. Fourth Line is located at 42.9599°N, 82.3219°W.
Fourth Line stretches across the flat, fertile expanses of Lambton, where the horizon holds a heavy, wide-open clarity that defines the local sky. It lies 2.4 km south of Sarnia, ON (from Sarnia, ON: bearing 188°T), and is situated 9.7 km south-west of Brights Grove. Under this vast dome, the land maintains a steady, industrious stillness, punctuated only by the distant, shallow breath of the Wawanosh Wetlands Conservation Area located just a few kilometres away. During the golden hour, the light pools across the fields with a syrupy weight, turning the dust of the road into a fine, shimmering haze that clings to the stalks of late-season crops. While the distant Lake Chipican sits eight kilometres to the west, the air here retains a crisp, inland quality, smelling faintly of turned earth and the impending shift of the seasons. The history of Fourth Line reflects the perseverance of those who first broke this heavy soil, establishing a legacy of agricultural endurance that persists in the modern economy. Local life moves according to the demands of the harvest and the maintenance of the homesteads, a tradition that keeps the pace of Fourth Line grounded in the practicalities of the land. Far to the southeast, the Bonnie Doon Creek winds its way through the landscape, serving as a quiet, flowing reminder of the natural hydrology that sustains the broader region. Residents here value a certain quietude, finding beauty in the stark, functional architecture of barns and the sturdy, unadorned character of the houses that stand as solitary sentinels against the wind.
