During 1862 the Company was increased by the fusion of Terrebonne, and l’Assomption and Lake St. Peter Lines with the Richelieu Company.

In 1861 the Montreal, costing $12,000, was placed on the line; in 1863 the Francois Yamaska was added, and in 1864 the Quebec was constructed at a cost of $172,000.

In 1875 the company line was further enlarged by the taking over of the line of boats running from Montreal to Toronto and Hamilton.

This amalgamation took the name of the Richelieu and Ontario Navigation Company and had a capital of $1,500,000 and eight steamboats. Four more were soon added, the Athenian and Abyssinian in 1876, the Cultivateur in 1880, and the St. Francis in 1883.

From 1876 to 1882 the late Sir Hugh Allan was president of the company, succeeded by L.A. Senecal, who died in 1887.

In 1895 Louis J. Forget became president of the company.

June 21, 1898, the company launched at Toronto, The Toronto, a handsome new steel steamer, costing about $250,000. In 1913 the Richelieu and Ontario became the Canada Steamship Lines Company, which amalgamation controls most of the freight and passenger boats operating in Canadian waters between the Gulf and the Great Lakes, except the Sincennes, McNaughton Line, which controls the towing in the district of Montreal, the Montreal Transportation Company, the Hall Forwarding Company and several smaller inland lines.

The Steamer Ontario, Captain Hilliard, was the first upper-deck steamer to descend Lachine Rapids, August 19, 1840. Her name was afterward changed to the Lord Sydenham.

It is not recorded that more than one steamer ever succeeded in ascending the rapids of the St. Lawrence River. In November, 1838, the little Dolphin, after four weeks of incessant toil, was towed up the Long Sault rapids with the aid of twenty oxen, besides horses, capstans and men, added to the working of her engine—the first and probably the last steamer that will ever accomplish the feat.
