What was the role/importance of Charles Tupper in the confederation of canada?

Tupper argued that Nova Scotia and the other Maritime colonies "could never hope to occupy a position of influence or importance except in connection with their larger sister Canada." As such, Tupper proposed to create a "British America", which "stretching from the Atlantic to the Pacific, would in a few years exhibit to the world a great and powerful organization, with British Institutions, British sympathies, and British feelings, bound indissolubly to the throne of England."
