Thornhill Baseball provides the fields, coaches, coaching development, player insurance, player uniforms, bats, and balls as a part of the registration fees.

Players must provide their own properly fitting baseball glove, safe batting helmet and shoes suitable for baseball.

For 5U, 7U, 9U and 11U divisions, players are also required to wear helmets with a face mask/cage to prevent injury.

During the registration process, each player may request to be on the same team with one friend. The request must be reciprocal, meaning the players must request each other on the submitted registration form.

Practices and games throughout the season are played at varying fields across Thornhill both within Vaughan and Markham. Field selection will be finalized once schedule is developed and released.
