What was the response in the federal government to the rise of Quebec separation?

The Canadian government has always stood in fierce opposition to Quebec separation. In reality the topic today has no real power, ever since the last referendum which was a close call, separation has been put on the back burner. Furthermore, with Chretien pushing through the Clarity Act, any attempt at separating would be a nearly insurmountable task. It allowed the government with quite a bit of control over any referendum question, and the determining of what constituted majority support. If you want to back further in history we can go back as far as Pearsons years in office when the first hints of seperatism are on the horizon. One notable event would be when Charles De Gaulle openly supported Quebec independence during a visit to Canada, and was subsequently asked by Pearson to no longer visit if he was going to promote such a thing. Now if we go to the Trudeau years with the October Crisis and the FLQ terrorist actions, this is where the federal government truly utilized its full power. So with the kidnapping of government officials, Pierre Trudeau utilized the War Measures Act to detain FLQ suspects and used the military to regain control of the situation. But as I said to begin with the separation movement has lost its steam. Today the Bloc Quebecois have other things to complain about, and Quebec has largely been courted by both Liberal and Conservatives governments in an attempt to one prevent seperatism to regain its popularity ( this has been done in ways such as when Prime Minister Harper allowe Quebec its on seat in UNESCO), and to mostly on the Conservatives part to regain their footing in Quebec. While the Liberals have always maintained a generally strong support in Quebec, the Conservatives have not ever since the Mulroney government in which he brokered an alliance between Western Progressive Conservatives and Quebec PC supporters. Of course these two groups stood very much against each other and it lead to the destruction of the PC party, the creation of the Canadian Reformers, and the Bloc.
