The Assembly for the Canadian Arts called a rally in support of the Symphony Six on May 29. The Toronto Musicians' Association instructed its members not to attend and sent members to stand outside the entrance "to intimidate members from entering". Aspersions were cast on the Assembly for the Canadian Arts as being a communist front organization, and the "Toronto Evening Telegram" called the gathering "a communist meeting". Several members of the Assembly quit the group in fear "of being labelled communists". On June 4 the United Church of Canada urged the TSO board to reconsider its decision.
