Édifice Jacques-Viger, Heritage architectural ensemble in Old Montreal, Canada

Édifice Jacques-Viger is a two-building complex at the corner of Saint-Antoine and Berri streets in Old Montreal. The six-storey Gare-hôtel Viger (700 Saint-Antoine East), built 1896–1898 by Bruce Price, has a style recalling the châteaux of the Loire. The Gare Berri (755–775 Berri), built 1910–1912, was two storeys until the city added a third in 1961.

The Viger station-hotel was built by the Canadian Pacific Railway between 1896 and 1898 to designs by Bruce Price, who also drew the Château Frontenac. It was the first building in Canada to combine a railway station and a hotel. The Berri station wing followed in 1910-1912, and Montreal added a third floor to it in 1961. The Canadian government occupied the complex from 1939 to 1950, first for military services and then to house veterans; the City of Montreal took it over from 1955.

The ensemble is named after Jacques Viger, Montreal's first mayor. Its two parts are known by their railway names: the Gare-hôtel Viger at 700 Saint-Antoine East and the Gare Berri at 755-775 Berri Street. The Viger building's style recalls the châteaux of the Loire, a reference visible in its roofline.

The building sits at the corner of Berri Street and Saint-Antoine Street East, within walking distance of Old Montreal's main attractions. A major renovation has improved accessibility throughout the structure, though some interior areas may have limited public access.

The Gare-hôtel Viger was the first building in Canada to combine a railway station and a hotel under one roof, built by the Canadian Pacific Railway in 1896–1898. Its architect, Bruce Price, also designed the Château Frontenac in Quebec City.
