Terra Cotta Brick Works before demolition.

The company produced hollow, fireproof terra cotta tiles. The clay was mixed with sawdust supplied by local farms. This product, for which the market was rapidly growing, was used for the construction of floors, walls and ceilings in a wide range of buildings, such as churches, theatres and schools. Given the success of the business, and in response to the demand, the company acquired new, modern and automated equipment. This equipment performed all phases of the manufacturing process up to firing. By 1925 more than 450 wagonloads of tiles were shipped out annually.

The business suffered a major fire in 1929 and was rebuilt. Terra Cotta employed up to 60 workers, and for a long time was the only manufacturing industry in Pointe-Claire. In 1962, approximately 700,000 cubic meters of clay had been extracted since its opening, and, the deposit exhausted, the factory was closed. The following year the company began to clean up the site. The main production building was found at the north end of the property, while kilns resembling small houses were located to the south, near the railway. Half of the site was sold to the municipality to create a park, and the rest was sold to the private sector for development. While it was active, the company allowed the community access to unused spaces. This explains the considerable private and public efforts to preserve the area as a park and bird sanctuary. The site of the clay quarry is now grassed over, while the remaining, much larger, area has been left in its natural state.
