As if the endless trails and waterfalls weren’t enough, Dundas is also home to the Urquhart Butterfly Garden. Named after pioneering entomologists Dr. Frederick and Norah Urquhart, who after forty years of patient research solved the mystery of the migrating monarchs, construction of Canada's first municipal butterfly garden began in 1994.Located in Centennial Park on the banks of the Desjardins Canal, it is heavily planted with nectar and foliage plants needed by butterflies and their caterpillars. It is maintained without the use of pesticides, many of which are detrimental to butterfly populations.
The garden now consists of six large raised beds, each approximately 75 × 35 feet, as well as the adjacent bank of the canal. All are planted with shrubs, perennials and annuals.
