Which of the following provinces is located farthest east in Canada?

Newfoundland and Labrador is the easternmost province in Canada, making it the correct answer. This province is situated on the eastern edge of the country, with its coastline extending into the Atlantic Ocean. Specifically, Cape Spear, located in Newfoundland, is recognized as the most easterly point in North America.

In contrast, while Ontario, Quebec, and Nova Scotia are also eastward provinces, they do not extend as far east as Newfoundland and Labrador. Ontario and Quebec are situated further to the west, with Ontario being central and Quebec more north-central. Nova Scotia is located to the southeast of New Brunswick and is east of Quebec, but it is still west of Newfoundland and Labrador. Therefore, Newfoundland and Labrador clearly stands out as the farthest east in Canada.
