Herein lay a difficulty for the postmaster general. The postal charges in Canada were the same as those in Great Britain, and were collected by the authority of the same act of parliament. The postmaster general was not free from doubts as to the legality of the proceedings of the post office in taking postage in Canada, and he did not wish to raise the question by the enactment of a special act for Canada. He intimated to Heriot his disinclination to bring the question into prominence in Canada, and asked Heriot to give his mind to the proposition for an improvement in the service.

About the time the letter from the postmaster general containing this instruction reached Heriot, Drummond himself wrote to Heriot, drawing attention to the shortcomings in the service, expressing his conviction that the necessary improvements would lead to enhanced revenues, and concluding with an intimation that unless he were provided with adequate facilities for communicating with that part of his command which was in Upper Canada, he would be obliged to restore military expresses.

Sir Gordon Drummond's services to Canada during the war were such as to entitle him to an honourable place in the memory of Canadians, but he did not appear at his best in his controversy with Heriot. He exhibited too much of that arbitrariness and impatience with other people's views which is commonly observed among military chiefs.

Heriot replied promptly to the governor's letter, stating that he had invited tenders for a semi-weekly service between Montreal and Kingston, and that the offers he received were quite beyond any possible revenue to be derived from the service. He had, however, accelerated the existing service by having the couriers travel on horseback, the horses being changed at convenient distances along the route.

As regards the service beyond York, Heriot directed the postmaster of York to arrange for a regular weekly courier to Niagara, and to set about securing a postmaster at Amherstburg to replace the former incumbent, who had resigned. Heriot wound up his letter by stating that he would have been particularly gratified if he had the power to meet his excellency's wishes in every point, but expressed his regret that his instructions obliged him to act on principles of economy.

The letter was courteously expressed, and showed an evident desire to go as far as his instructions would allow, in meeting the governor's wishes. But Drummond was not satisfied. His wrath rose at the appearance of opposition. In repeating his views that increased revenue would follow upon improvements in the service, he declared that the existing arrangements were slovenly and uncertain, and, in the opinion of merchants, insecure. Moreover, he did not believe that Heriot's instructions were intended to be injurious to the interests of Upper Canada.

Drummond then most unreasonably found fault with Heriot for leaving to Allan the duty of attending to the requirements of Niagara and Amherstburg, when his excellency had ordered Heriot to give the matter his personal attention. Heriot's time was very fully occupied at Quebec with the ordinary duties of his office, a fact of which Drummond could not have been ignorant; and to order him to leave these duties, and make a journey to the western end of the province, involving a travel of scarcely less than twelve hundred miles, to do a piece of work which any subordinate in the district could do equally well, argued either an indifference as regards the daily calls upon Heriot's time, or a determination to annoy him, either of which was discreditable to the governor general.

Heriot was steadily respectful, however, but maintained that with the powers entrusted to him it was impossible to meet Drummond's views. He cited the incident of 1812, when his recommendation that the whole of the revenue from Upper Canada should be expended on extensions and improvements had been disapproved, and the arrangements founded upon these suggestions had to be cancelled. As for his employment of Allan to secure a postmaster at Amherstburg, Allan knew the district while he himself did not, and in his circumstances he was compelled to rely upon his officials as he did in the west and at Halifax.

The whole of the case was laid by Heriot before the postmaster general. His situation, he declared, was very disagreeable, as people seemed to imagine that he had carte blanche as to the disposal of the post office revenue. Every governor on coming to Canada assailed Heriot with his particular scheme for improvement. Prevost, who had come from the governorship of Nova Scotia, insisted on a large expenditure on the service in that province. Drummond, whose interests lay in Upper Canada, was peremptory in regard to the claims of that part of the country. The consequence of all this was correspondence always lengthy and frequently unpleasant.

What Heriot desired to know was whether his conduct was approved or condemned by his superiors. The official silence left him in uncertainty and suspense. Heriot concluded by asking to be relieved of the office and to be allowed some remuneration for past services.
