Much of Quebec is high land, which can afford ample escape from the coastlines during the hour of the shift for residents. The majority of Quebec Province will remain above water after the existing poles have melted. The climate will be more moderate than today, especially after the ice of Greenland melts and the near proximity from that great meltoff no longer creates cold tides on the shore of Quebec. The greatest concern that Quebec will have after the shift will be migrating survivor from the population centers of eastern half of the US. Crowded up into the Appalachian Mountains and into the limited land mass that the New England area provides, they will be as likely to push into Quebec as toward what were the western states of the US, seeking land that would have been high enough to remain dry land. As an essentially rural province, Quebec will not be prepared for the aggressive insistence that those along the eastern seaboard of the US have as their normal stance in life. Residents of New York and Washington DC in particular, are used to getting their way by being loud mouthed and insistent. Some forethought into how to handle such migrants when the time comes should be part of the Quebec survival plan.

Your latitude after the pole shift will put you in a warmer climate than currently. Compare the distance from the new N Pole off the Bulge of Brazil to the Equator, against the distance from Quebec to the new Equator. Even with the S American Plate crushing much of the Caribbean and Central America, this will still be the case, a warmer climate. It is true that land bridges to Quebec will flood during the rising seas after the pole shift, though the highlands of Quebec will remain above the waves. But isolation will hardly result nor will all land bridges to flooded. Many in the flooded north, in Canada, will migrate to Quebec, and we have warned that many from the East Coast of the US will become what might prove to be unwelcome guests. Quebec is likely to be a very lively location in the future!
