The Festival de Lanaudire notified the MSO that it had been replaced with other orchestras for the four July concerts that it had been scheduled to perform.
In addition, the Mondial choral de Laval canceled the orchestra's June 28 appearance at its June 28.
A statement released by orchestra management said that management "is well aware of the constraints of the Mondial choral de Laval and of the Festival de Lanaudire. . . These organizations must fulfill commitments and hold these concerts, despite the situation prevailing at the orchestra."
The musicians went on strike on May 9, after playing without a contract for nearly two years. Musicians and management have not been able to come to an agreement regarding the orchestra's work rules and salaries.
