Patriation was given a new impetus after the 1980 referendum on Quebec independence, before which Trudeau promised a new constitutional agreement if the majority of Quebecers voted "No". After a number of days of negotiation and the leak of the Kirby Memo which antagonized Quebec, by an "internal federal source", after provincial premiers consulted at the Chateau Laurier, drafted a list of 10 powers to be devolved to the provinces in exchange for consent to patriation. Trudeau, when presented with the document, refused to accept it and reiterated his threat that he would seek the House of Commons' approval to proceed with a unilateral amendment. Faced with Premier of Manitoba Sterling Lyon's charge that it would "tear the country apart", Trudeau responded that, if Canada could not have control of its own constitution and a charter when most provinces had their own, the country would deserve to be torn apart.
