New Windsor sits across the Detroit River from the GLMZ's industrial heartland, and that proximity defines everything about it. The Ambassador Bridge — reinforced, widened, and draped in sensor arrays — and the Detroit-Windsor Tunnel form the two arteries connecting Canadian sovereign territory to the American corporate zones, and every drop of commerce that flows between them gets taxed, scanned, and surveilled twice. Once by each side. The result is a city that exists primarily as a jurisdictional membrane — a place where goods, people, and data change legal status simply by crossing a river.

The old automotive plants that once built cars for the North American market have been retooled into fabrication centers for neural interface components, autonomous vehicle subsystems, and military-grade augmentation hardware. Tessera Corponation and Zheng-Dao Bioelectric both maintain sovereign manufacturing enclaves here, exploiting the dual-sovereignty arrangement to dodge regulations on both sides of the border. Workers commute between jurisdictions daily, their legal rights flickering on and off like a bad connection as they cross the river. Canadian labor protections apply on the north bank. Corporate sovereign law applies on the south. The tunnel between is a legal no-man's-land where neither applies and everyone knows it.

The residential districts sprawl south and east from the riverfront, a patchwork of climate-refugee housing blocks, mid-tier corporate dormitories, and the decaying bones of twentieth-century suburbia that nobody has bothered to demolish. The population skews young, transient, and bilingual in ways that have nothing to do with French and English — Shelf Cant, Mandarin trade pidgin, and machine-interface shorthand are the languages that actually matter here. The city smells like ozone and river water, and on bad days the chemical plumes from Sarnia drift east and add a third note that makes your eyes water.
