He was elected to the legislature in the
1943 provincial election by defeating incumbent Conservative MPP
William Summerville but was defeated in
1948 by
Gordon Millen. Wismer was again elected for a second, and final, term in
1948. During his first term he acted as the party's financial critic. In 1951, Wismer took exception to a $6,000 grant to the
Art Gallery of Toronto for the purchase of two busts by
Picasso and
Matisse. He appraised the busts as showing "just how hideous some things can be." He also said that such art could be interpreted as a set of symbols that lead one to believe that "our Christian civilization is disappearing." He went further to say that he didn't want the legislature to decide on the aesthetic value of art but just to find out what the gallery paid for these two pieces before granting the money. Wismer's stand was criticized by
Labor-Progressive (Communist) MPP
Joseph Salsberg who proclaimed "it will be a sorry day when politicians assume the role of arbiters in art." The house voted to allow the grant. At the end of his second term he decided not to run again. He said that his work responsibilities with the Canadian Labour Congress did not leave him enough time to devote to legislature and riding activities. ==Later life==
