Rockland is a bilingual community located about 40 kilometers (25 miles) east of downtown Ottawa, Ontario, Canada, part of the city of Clarence–Rockland. Rockland has a population of 9,210.

The Clarence region began growing in 1840 with the development of the road to l'Orignal-Bytown. Before then, farmers relentlessly cleared wooded space to be able to cultivate land, their only survival mean. In 1868, a young entrepreneur, William Cameron Edwards, decided to establish a sawmill at the McCaul point. The opening of link to the Grand Trunk Railway followed in 1888 to allow wood and merchandise to be transported. Edwards, who held timber rights in the area and was also the first postmaster, named the area for the rocky nature of its landscape.

In 1889, the mission served by the priest Caron from Clarence-Creek became a parish. The first priest of the new parish was Siméon Hudon, native of Québec City. The first school opened in 1875 while the first high-school opened in 1905.

Construction of a second railroad in 1908 linking Ottawa and Hawkesbury greatly promoted population. In effect, for .75 cents (return) people could go to Ottawa to run errands and return in the same day. The woodmill owned by W. C. Edwards closed its doors in 1926, as a result of the economic turmoil following the First World War. A large part of the population moved to the Quebec province to find employment in the woodmills in Hull and Gatineau. The economic recovery began in 1939 with the start of the Second World War. The return of soldiers after the war brought an increase in population. Construction of homes increased rapidly creating a need for expanded water services, electricity and a sewer system implemented in 1964.
