Much had already been spent on the improvement of inland navigation, and the early fifties saw the beginning of a great advance in railway construction. The Intercolonial Railway to connect the Maritime Provinces with Canada was projected as early as in 1846, though inability to agree upon the route delayed construction many years. In 1853 the Grand Trunk was opened from Montreal to Portland in Maine. The Great Western (now a portion of the Grand Trunk system), running between the Niagara and Detroit rivers, was opened during the following year; and 1855 witnessed the completion of the Grand Trunk from Montreal to Brockville, and the Great Western from Toronto to {49} Hamilton. The Detroit river at that time marked the western limit of settlement in Canada. North and west stretched a vast lone land about which scarcely anything was known. The spirit of enterprise, however, was stirring. The expiry of certain trading privileges granted to the Hudson's Bay Company in 1838 offered the occasion for an inquiry by a committee of the Imperial House of Commons into the claims of the company to the immense region associated with its name. The Canadian Government accepted an invitation to be represented at this investigation, and in the early part of the year 1857 dispatched to England Chief Justice Draper as commissioner. The committee, which included such eminent persons as Lord John Russell, Lord Derby, and Mr Gladstone, reported to the effect that terms should be agreed upon between the company and the Imperial and Canadian governments, in order that the territory might be made available for settlement; but no further steps were then taken. The question was not to be settled until some years later.
