Statement of Significance

Description of Historic Place

Senneville Historic District National Historic Site of Canada evolved from a late-19th-century resort village located on the shores of the Lac des Deux-Montagnes, at the western tip of the Île de Montréal. The district comprises more than 1400 acres and includes at least 82 buildings constructed between 1860 and 1930 as part of about a dozen country estates. The main thoroughfare of the district is chemin Senneville, a country road that runs parallel to the shoreline of the lake. The buildings are set well back from the road within large, wooded estates, many of which back onto the lake. The buildings include large manor houses, as well as smaller secondary residences, agricultural outbuildings and landscape elements. The district features a range of picturesque landscapes and Arts & Crafts-inspired architecture. It includes the ruins of Fort Senneville and the Senneville windmill, the Morgan Arboretum, a nature park (l’Anse-à-l’Orme) and an agricultural park (Bois-de-la-Roche) all of which are components of estate lands, as well as Braeside, a late 19th-century golf course. These latter four elements form an extensive greenbelt along the southern and eastern edges of the district which separates it from adjacent residential and industrial development. Official recognition refers to the historic district and its constructed and natural features at the time of designation.

Heritage Value

Senneville Historic District was designated a national historic site of Canada in 2001 because:
- it illustrates the synergy created between the major Montréal financiers at the turn of the 20th century and some of the greatest Canadian architects of the period;
- it illustrates the development of Picturesque landscape design, as well as vernacular and Arts and Crafts architecture from 1865 to 1930;
- it includes several recognized examples and masterpieces from the history of Canadian landscape design and architecture.

The estate owners of Senneville were the founders, presidents or directors of some of the largest commercial enterprises of the period, including the Bank of Montreal and the Canadian Pacific Railway. They included: Sir John Joseph Caldwell Abbott (1821-1893), Mayor of Montréal and Canada’s third Prime Minister; John Lancelot Todd, professor of parasitology at McGill University; Louis-Joseph Forget (1853-1911), a stock broker and Conservative senator; and Montréal bankers Sir Edward Seaborne Clouston (1849-1912) and Richard Bladworth Angus (1831-1922).

The Senneville Historic District includes more than 30 major projects designed by a small group of eminent Montréal architects, landscape architects and urban planners, often working in collaboration with American designers. This group included some of Canada’s greatest architects and designers of the period. They shared a picturesque approach to landscape design, an eclectic approach to architecture and an affinity for the Arts & Crafts Movement. At the heart of the Montréal group were brothers Edward Maxwell (1867-1923) and William Sutherland Maxwell (1874-1952), who designed dozens of Senneville buildings, sometimes working in partnership with Montréal architect George Cutler Shattuck (1864-1923). The 20 Maxwell buildings that survive constitute a unique example in a single location of their work. Montréal architect and professor Percy Erskine Nobbs (1875-1964), in partnership with George Taylor Hyde (1879-1944), designed the buildings and grounds of the J.L. Todd estate. Landscape architect and urban planner Frederick G. Todd (1876-1948), working with American landscape designer Frederick Law Olmsted, designed the grounds of the Abbott/Clouston estate. Olmsted also designed the grounds of the Forget estate. Other eminent Montréal architects responsible for the designs of Senneville buildings included: James & H. Charles Nelson; Kenneth Rea (1878-1941); Harold Edgar Shorey (1886-1971); Samuel Douglas Ritchie (1887-1959); J.R. Hind; Robert Findlay (1859-1951); Frank R. Findlay; and David Shennan.

Built between 1860 and 1926, the Senneville estates and their buildings illustrate the development of the Arts & Crafts movement and Picturesque landscape design during this period in Canada. Because they were created by a small number of owners using a limited group of architects and designers over a relatively concentrated period of time, the buildings and landscapes of Senneville have a strong formal and stylistic coherence.

The Senneville Historic District includes several recognized masterpieces of Canadian architecture and landscape design, including “Bois-de-la-Roche”, the Château-style residence built by Senator Louis-Joseph Forget; and the J.L. Todd estate.
