2. England: John Cabot, an Italian explorer sailing under the English flag, is credited with the discovery of the mainland of North America in 1497, specifically parts of Canada's east coast.

3. France: Jacques Cartier, a French explorer, made three major voyages to North America in the 16th century. He is best known for exploring the St. Lawrence River, allowing France to lay claim to lands that would become Canada.
