This is a reprint of the article "Behind Closed Doors," by Brian Mulroney that appeared in the June 15, 1987 issue of "Maclean's." Prime Minister Brian Mulroney was asked to write this account of the marathon bargaining session that led to the June 3, 1987, Meech Lake constitutional agreement. We met for almost 20 consecutive hours, from mid-morning of one day to the dawn of the next. We were 11 Canadians, from diverse backgrounds, from different political parties and different regions of Canada. Around that oval table, in the fourth-floor boardroom of the Langevin Block, all the partners of Canada were trying to finalize a new deal for Canada. We were trying to accommodate Quebec's agenda and that of the other regions, within the national interest, and in a manner consistent with the responsibilities of the national government. People were getting pretty tired, but I had made it quite clear that we were going to go on until we either got an agreement, or didn't. But we still had to finalize the spending power, and that proved to be a tough one, too. Resolving the issue of Quebec's signature on our Constitution was one of the reasons I went into public life four years ago, and why some people, at considerable personal sacrifice, agreed to come to Ottawa with me. Since 1982, we have been witnessing the slow but measurable emergence of two Canadas -- one representing those who had accepted the Constitution, and the other those who had not.
