Grand Trunk Railway: Map, History, Timetables

Last revised: September 9, 2026

The Grand Trunk Railway Company of Canada (reporting mark GT) was British capital’s main line in the Province of Canada: Montreal to Toronto, then east to an ice-free port at Portland, Maine, and west to Sarnia and Chicago. It was chartered on November 10, 1852. The Montreal–Toronto main opened in October 1856. By Confederation it was already one of the longest railways under one management in the world. It took the Great Western in 1882, bored the St. Clair Tunnel in 1891, and then wrecked itself building a third transcontinental. The Grand Trunk Pacific and the National Transcontinental pulled the parent into default. Canadian National took the property on January 20, 1923.

This page is that company. The Michigan and Indiana lines that outlived the name are Grand Trunk Western. The New England corridor is Central Vermont. The Crown corporation that swallowed the Grand Trunk is Canadian National. The parallel Detroit–Chicago competitor is Michigan Central.

November 10, 1852

The Province of Canada wanted a trunk between its two cities that mattered, Montreal and Toronto, and an outlet that did not freeze. Francis Hincks pushed the 1852 act. The English contractors Peto, Brassey, Jackson & Betts took the work in return for promoting the company in London. Capital was sterling. The board sat in London for the rest of the company’s life. Montreal ran the railroad.

The charter grew at once: east to Portland, west toward Sarnia. The Grand Trunk did not lay every mile as new construction. It bought and leased what already pointed the right way.

Portland, and 5 foot 6

In 1853 the Grand Trunk took the St. Lawrence & Atlantic from Montreal to the Vermont line and leased the Atlantic & St. Lawrence, the U.S. company that finished the line to Portland. Britannica dates the Montreal–Portland link complete in July 1853 and calls it North America’s first international railroad. Portland gave the Province of Canada a winter port that Montreal and Quebec City could not. That New England stem is not a later invention called “Grand Trunk Eastern.” It is the Atlantic & St. Lawrence, later operated as Grand Trunk in Maine, New Hampshire, and Vermont, alongside the separate Central Vermont.

The Provincial Gauge was 5 ft 6 in. Interchange with standard-gauge American roads meant breaking bulk or a third rail. The Grand Trunk converted to 4 ft 8½ in in the 1870s, commonly dated 1872–74. After that, Portland and Chicago were the same gauge.

Montreal, Toronto, Sarnia

Montreal to Toronto opened in October 1856—about 334 miles of Peto & Brassey main line along the north shore of Lake Ontario. The Toronto & Guelph, already under construction, was taken in 1853 and bent toward Sarnia instead of its original end. Gzowski, Holton, MacPherson and Galt built Toronto–Sarnia. That western end opened in November 1859. A ferry across the St. Clair River to Fort Gratiot (Port Huron) started the same year. A Port Huron–Detroit line, promoted by men around the Grand Trunk board, opened in 1859 and was leased to the Grand Trunk in 1860.

East of Montreal the company built Montreal–Richmond–Lévis (1854–55) and pushed downriver toward Rivière-du-Loup, the “Maritime connection” that Confederation would later finish as policy. By 1860, with the Victoria Bridge in service, Portland to Sarnia was about 800 miles under one management. Period writers called it the longest railway in the world so owned. By 1867 the figure often quoted is more than 1,277 miles, Portland to Rivière-du-Loup plus the Ontario main and the New England feeders.

Victoria Bridge

Robert Stephenson and Alexander M. Ross designed a tubular bridge across the St. Lawrence at Montreal. The first train ran on December 19, 1859. The Prince of Wales (later Edward VII) opened it officially on August 25, 1860. It was the first permanent crossing of the river there and the reason Portland traffic did not have to ferry in winter. The tubes came out in the 1890s. The present truss, on the same piers, dates from 1898. CN and VIA still use the alignment.

Great Western, 1882

The Great Western Railway of Canada was the Grand Trunk’s Ontario rival: Niagara, Hamilton, London, Windsor, and a Michigan stake. The two fought for Chicago traffic and for the Michigan Central connection. In 1882 the Grand Trunk absorbed the Great Western, about 904 miles. Niagara mileage and the old Roebling road-and-rail suspension bridge of 1855 came with the merger. Hays replaced that span with a steel arch opened September 24, 1897. The International Bridge at Fort Erie–Buffalo is the other Niagara crossing on this map. Do not confuse either with Michigan Central’s Canada Southern and Detroit River tunnels.

Chicago itself was a Grand Trunk Western problem. The Port Huron–Chicago line, in place by 1880, is the GTW story. The parent used it as the western end of Portland–Chicago. The GTW kept its own name and, long after 1923, its own paint, into 1991.

St. Clair Tunnel, 1891

The ferry at Sarnia was a bottleneck in ice. The St. Clair Tunnel Company, a Grand Trunk subsidiary, bored under the river between Sarnia and Port Huron. Freight used the tunnel in 1891; passenger trains the next year. It is not the Michigan Central Detroit River tunnels of 1910. Two international tunnels, two railroads, two rivers. The 1891 bore was later enlarged for modern clearances; CN still uses the corridor.

Other 1880s–90s plant: double track Montreal–Toronto begun 1887 and finished 1903; Bonaventure Station, Montreal, 1888. Charles Melville Hays, hired from the Wabash as general manager on January 1, 1896, spent money on brakes, grades, and bridges and finally made the Grand Trunk show a profit. He became president in 1909. He also took the company west.

Hays, and the Pacific that killed it

After Confederation the government asked the Grand Trunk to build to British Columbia. The company said no. Ottawa chartered the Canadian Pacific instead; CP reached the Pacific in 1885. Watching immigration and CP’s prairie business, the Grand Trunk reversed itself. Talks with Canadian Northern failed. In 1903 Hays and the Laurier government agreed on a third transcontinental. The Grand Trunk would build and operate the Grand Trunk Pacific from Winnipeg to Prince Rupert via Yellowhead Pass, with federal help. The government would build the National Transcontinental from Winnipeg to Moncton via Quebec City; the Grand Trunk would operate that too.

The Grand Trunk took control of the Canada Atlantic (Ottawa to Vermont and to Georgian Bay) in 1905; Parliament confirmed the purchase in 1914. GTPR construction began in 1905. The line opened in 1914. The NTR opened in 1915, minus a finished Quebec Bridge. The GTPR sat north of CP in the Prairies. The NTR sat north of the population in Ontario and Quebec. Yellowhead was the easiest divide crossing on the continent. It did not make the traffic.

Hays died on the Titanic on April 15, 1912. The system stopped for five minutes on April 25. The Southern New England Railway, a 1910 scheme for a Grand Trunk line to Providence, died with him, unfinished. Management of the Pacific project did not improve.

Default

The Grand Trunk refused to operate the National Transcontinental, citing the economics. GTPR construction costs overran. In 1919 the parent could not meet its loan obligations on the Pacific. GTPR was nationalized on March 7, 1919, run by a federal board, and placed under Canadian National on July 20, 1920. The Grand Trunk itself went under another federal board on July 12, 1920. British shareholders fought nationalization. An arbitration board found the stock had no value. Order in Council of January 19, 1923, vested the preference and common in the Minister of Finance. On January 20, 1923, Canadian National took operation. About 125 companies, 8,000 miles in Canada, 1,164 in the United States.

Canadian National, not a second Grand Trunk, is the successor encyclopedia. The Grand Trunk name survived in the United States as Grand Trunk Western and, for a time, as CN’s New England marketing. That is not this charter still running.

1893 Official Guide

The plates below are the Grand Trunk listing in the 1893 Official Guide of the Railway and Steam Navigation Lines of the United States and Canada—the same year as the system map. Read them as a period document, not a 2026 timetable. Portland, Montreal, Toronto, Sarnia, and the Michigan lines are the railroad that still had not gone west of Winnipeg.

What still runs

The Montreal–Toronto trunk is still a railroad: Canadian National freight and VIA Rail corridor trains. The Victoria Bridge alignment still carries that traffic across the St. Lawrence. The St. Clair Tunnel corridor is still CN’s Detroit access, parallel to CPKC’s Detroit River tunnels on the Michigan Central. Port Huron–Chicago is still the old Grand Trunk Western, now CN. The Portland–Montreal line still moves freight as the St. Lawrence & Atlantic. Central Vermont became New England Central in 1995.

The Grand Trunk Railway Company of Canada does not exist. It lasted seventy years. The map it left is still the spine of central Canada and CN’s way into Chicago and New England.
