The paper was originally launched as The Presbyterian and Evangelical Protestant Union in the 1870s, owned by Stephen G. Lawson. The current name of the paper was adopted in 1887. The paper had a sister publication, The Evening Patriot, which was discontinued in 1995. The slogan of The Guardian for many years has been “Covers the Island like the dew” and it remains principally a Charlottetown publication.

This weekly newspaper started as the Summerside Journal in 1865 which was founded by two men named Bernard and Bertram. The Journal began publishing on September 21, 1939 as a daily, in order to provide regular news of World War II. After the war, the paper cut down to twice-weekly publication, then tri-weekly in 1949 after it closed a sister paper, The P.E. Island Agriculturalist. The Pioneer was founded in 1876 in Alberton, moving to Summerside in 1880. The papers were merged into the Journal-Pioneer in 1951, and adopted a daily weekday publishing schedule in October 1957. After two years, a Saturday edition was added.

The Cadre is a student-run newspaper at the University of Prince Edward Island in Charlottetown, Prince Edward Island. In December 2002, the paper published a satirical article that was written to address the issue of consumerism during the Christmas season that references to suicide, murder and rape. The said article offended enough people to have support for The Cadre withdrawn by the UPEI Student Union. The paper drew harsh criticisms when it became the first North American publication to print the offensive Muhammad cartoons. While in Spring 2014, the Cadre came under fire for publishing an article criticizing students’ clothing during a beach-themed event. The paper moved to an online-only publication model in 2012.
