The Grand Trunk Railway Company of Canada was formed in 1852 as a
consolidation of several railways, some under construction, others only
projected. It became one large system stretching from Levis, Quebec (already
connected to Montreal) all the way to Sarnia, Ontario (and extending to
Windsor). it was eventually fully merged into Canadian National.
The corridor is VIA's busiest route, running more than 400 of Canada's
intercity passenger trains on tracks throughout the corridor every week, using
CN's former Grand Trunk Railway network. Traffic in the corridor represents
close to 90% of VIA's volume or more than 3.5 million trips, which means that
VIA derives the majority of its revenues from this route.
