The Trans-Canada Highway was built to connect a nation. In 2200, it connects a series of corporate sovereign enclaves that happen to share a national flag. The Trans-Canada Corridor runs 1,900 kilometers from New Windsor to Grainfort, following the Lake Huron and Lake Superior shorelines through some of the most sparsely populated territory in the GLMZ. The highway has been upgraded — widened, automated, and partially enclosed against the climate — but the distance remains. The distance is the point. The TCC is not a highway so much as a logistical argument against Canadian geography, a continuous assertion that these cities are connected despite every natural feature suggesting they shouldn't be.

Ferrogate Transit and Stonepath Logistics share the corridor's operating charter, dividing the route at Lockhaven North — Ferrogate handles Windsor to the Soo, Stonepath handles the Soo to Thunder Bay. The arrangement is competitive rather than cooperative, and the service quality varies accordingly. The Ferrogate section — running through the populated southern corridor past London, Kitchener, and The Lattice — is twelve lanes, fully automated, and maintained to GLMZ infrastructure standards. The Stonepath section — running along the Superior shore through towns that are barely towns — is six lanes, partially automated, and maintained to whatever standard Stonepath's quarterly budget allows. The gap between the two sections is visible from a vehicle window and legible as a statement about economic priorities.

The corridor's most critical function is not passenger transport but data. Fiber-optic trunk lines run beneath the highway surface, carrying 40% of the GLMZ's Canadian data traffic. Bathysphere Networks maintains the fiber infrastructure under a separate sovereignty charter, and their relay stations — positioned every 50 kilometers along the corridor — are the physical backbone of the Canadian net. Severing the TCC doesn't just stop traffic. It partitions the Canadian internet. This fact makes the corridor critical infrastructure in the military sense, and the security presence reflects it — Canadian military checkpoints at key positions, automated surveillance along the entire route, and the understood reality that attacking the TCC is an act of war against the data it carries, not just the vehicles.
