text: who won the french and indian war?   the war officially ended with the signing of the treaty of paris on february 10, 1763. the treaty resulted in france's loss of all its possessions in north america (all of canada was ceded to britain) except saint pierre and miquelon, two small islands off newfoundland. france also kept the caribbean islands of guadeloupe and martinique because of their rich sugar crops and the ease with which it could be controlled. spain gained louisiana in compensation for its loss of florida to the british.  one result of the war was that britain gained control of a strip of territory along the st. lawrence river that now forms part of the province of quebec with approximately 54,000 french-speaking, roman catholic population. near the beginning of the war, in 1755, the british had expelled french-speaking populations in acadia to louisiana, creating the cajun population, but this would not be repeated in 1763.  the european theater of the war was settled by the treaty of hubertusburg on february 15, 1763.
