Sir Richard Cartwright, then a young member of parliament, relates an incident illustrating the tension on men's minds at that time. He says: "On that memorable afternoon when Mr. Brown, not without emotion, made his statement to a hushed and expectant House, and declared that he was about to ally himself with Sir Georges Cartier and his friends for the purpose of carrying out confederation, I saw an excitable, elderly little French member rush across the floor, climb up on Mr. Brown, who, as you remember, was of a stature approaching the gigantic, fling his arms about his neck and hang several seconds there suspended, to the visible consternation of Mr. Brown and to the infinite joy of all beholders, pit, box and gallery included."[15]

The official account given by Mr. Macdonald in the House, is that immediately after the defeat of the government on Tuesday night (the 14th), and on the following morning, Mr. Brown spoke to several supporters of the administration, strongly urging that the present crisis should be utilized in settling forever the constitutional difficulties between Upper and Lower Canada, and assuring them that he was ready to co-operate with the existing or any other administration that would deal with the question promptly and firmly, with a view to its final settlement. Mr. Morris and Mr. Pope, to whom the suggestion was made, obtained leave to communicate it to Mr. John A. Macdonald and Mr. Galt. On June 17th Mr. Macdonald and Mr. Galt called upon Mr. Brown. In the conversation that ensued Mr. Brown expressed his extreme reluctance to entering the ministry, declaring that the public mind would be shocked by such an arrangement. The personal question being dropped for the time, Mr. Brown asked what remedy was proposed. Mr. Macdonald and Mr. Galt replied that their remedy was a federal union of all the British North American provinces. Mr. Brown said that this would not be acceptable to Upper Canada. The federation of all the provinces ought to come and would come in time, but it had not yet been thoroughly considered by the people; and even were this otherwise, there were so many parties to be consulted that its adoption was uncertain and remote. He expressed his preference for parliamentary reform, based on population. On further discussion it appeared that a compromise might be found in an alternative plan, a federal union of all the British North American provinces or a federal union of Upper and Lower Canada, with provision for the admission of the Maritime Provinces and the North-West Territory when they desired. There was apparently a difference of opinion as to which alternative should be presented first. One memorandum reduced to writing gave the preference to the larger federation; the second and final memorandum contained this agreement: "The government are prepared to pledge themselves to bring in a measure next session for the purpose of removing existing difficulties by introducing the federal principle into Canada, coupled with such provisions as will permit the Maritime Provinces and the North-West Territory to be incorporated into the same system of government. And the government will, by sending representatives to the Lower Provinces and to England, use its best endeavours to secure the assent of those interests which are beyond the control of our own legislation to such a measure as may enable all British North America to be united under a general legislature based upon the federal principle."

It was Mr. Brown who insisted on this mode of presentation. At the convention of 1859 he had expressed in the strongest language his hope for the creation of a great Canadian nationality; and he had for years advocated the inclusion of the North-West Territories in a greater Canada. But he regarded the settlement of the difficulties of Upper and Lower Canada as the most pressing question of the hour, and he did not desire that the solution of this question should be delayed or imperilled. Galt's plan of federation, comprehensive and admirable as it was, had failed because the assent of the Maritime Provinces could not be secured; and for five years afterwards no progress had been made. It was natural that Brown should be anxiously desirous that the plan for the reform of the union of the Canadas should not fail, whatever else might happen.

On June 21st, Mr. Brown called a meeting of the members of the Opposition for Upper Canada. It was resolved, on motion of Mr. Hope Mackenzie, "that we approve of the course which has been pursued by Mr. Brown in the negotiations with the government, and that we approve of the project of a federal union of the Canadas, with provision for the inclusion of the Maritime Provinces and the North-West Territory, as one basis on which the constitutional difficulties now existing could be settled." Thirty-four members voted for this motion, five declining to vote. A motion that three members of the Opposition should enter the government was not so generally supported, eleven members, including Alexander Mackenzie and Oliver Mowat, voting in the negative. The Lower Canadian Reformers held aloof, and in the subsequent debate in the legislature, strongly opposed confederation.

There were many evidences of the keen interest taken by the governor-general (Monk) in the negotiations. On June 21st he wrote to Mr. Brown: "I think the success or failure of the negotiations which have been going on for some days, with a view to the formation of a strong government on a broad basis, depends very much on your consenting to come into the cabinet.

"Under these circumstances I must again take the liberty of pressing upon you, by this note, my opinion of the grave responsibility which you will take upon yourself if you refuse to do so.

"Those who have hitherto opposed your views have consented to join with you in good faith for the purpose of extricating the province from what appears to me a very dangerous position.

"They have frankly offered to take up and endeavour to settle on principles satisfactory to all, the great constitutional question which you, by your energy and ability, have made your own.

"The details of that settlement must necessarily be the subject of grave debate in the cabinet, and I confess I cannot see how you are to take part in that discussion, or how your opinions can be brought to bear on the arrangement of the question, unless you occupy a place at the council table.
