Here are some possibilities resulting from a Quebec seperate from Canada. Some are likely, some are not. ALL of them I have heard seriously discussed in the past in both the US and Canada.

1. The Maritimes apply for Statehood and inclusion in the US, as they are seperated from the rest of Canada.

2. The price of petroleum and other products in Quebec rises considerably, as they are no longer affected by Canadian controls.

3. In a joint move, US and Canadian forces seize the St. Lawrence River and Seaway, as well as other defense installations.

4. The capitol is moved from Ottawa to someplace further west, perhaps to Manitoba.
