Montreal to continue her career at 6 Beaver Hall Square, she reached a sizable new audience that regarded her as the premier Canadian portraitist of children. Her work received recognition both in Canada and beyond. She received a silver medal at the 1901 Pan-American Exposition and was awarded a bronze medal at the 1904 Canadian exhibition at the Louisiana Purchase Exposition in St. Louis, Missouri. She showed 27 paintings with the Royal Canadian Academy of Arts between 1893 and 1929, and exhibited in yearly exhibitions at many other societies and associations. Her earlier submissions to shows were frequently compared and contrasted with that of her contemporary and friend Florence Carlyle, but in time, her work was applauded in its own right, especially for her sympathetic, lucid manner. Critics recognized that her work looked created by chance, but was the result of years of observation and work, as Le Canada wrote in 1903. She was elected as an associate member of the Royal Canadian Academy of Arts in 1896, only the eighth woman to receive this honour. Muntz was a member of the Ontario Society of Artists starting in 1891; she was the first woman appointed to its Executive Council in 1899, serving until 1903. In 1909, she was invited to exhibit with the Canadian Art Club: she was the only woman so honoured by this group. Following the death of her sister in 1915, she returned to Toronto and married her brother-in-law Charles W.B. Lyall to care for the children of her sister's marriage (there were 11 of them but only a few remained at home). She then set a studio up in the attic of their home, and started signing her works with her married name. In 1921, she travelled with her husband to Devon, England and there painted what was new scenery for her. Critics praise her handling of light and restrained though rich colour, proof that she could have been a major landscape painter if she chose. In 1930, Muntz was ill and dying of Exophthalmic Goitre brought on partly by overwork and worry about the family responsibilities she had assumed fifteen years earlier. Despite these trying personal circumstances, she continued to paint until her death in 1930. Lyall is interred in the Mount Pleasant Cemetery in Toronto. Collections Both the National Gallery of Canada and the Art Gallery of Ontario include her work in their holdings.
