Program Information


Great Person. Great Athlete. Great Player.

The core philosophy of Leaside Baseball is to help players learn the game and develop their skills in a safe, positive, inclusive, and fun environment. 

We welcome boys and girls of all experience levels.

Through the teaching and refining the fundamentals of baseball – throwing, catching, hitting, running, jumping, sliding and much more – your child will gain a greater understanding of the game. Learning in a fun and supportive environment, players become more comfortable and skilled with the movements.


Instructional Highlights

  • Demonstration and hands-on practice of correct hitting, fielding, base running, throwing and catching mechanics
  • Baseball instruction, drills and situational game play scenarios
  • Batting practice and hitting drills using machines, instructor toss and tees
  • Baseball-specific athletic training to improve upon speed, agility, hand-eye coordination, balance, strength and flexibility

His specialized development instruction and training is matched by his creativity and passion for working with young players. He’s a player and parent favourite in our organization.



The LBA also provides all required baseball equipment including balls, bases, bats, and helmets. Equipment will be sanitized periodically during the session

Players should wear comfortable athletic clothing, a mask that comfortably covers their mouth and nose, appropriate running shoes or indoor cleats, and an athletic cup is required for age 8 and older. They should bring their baseball glove and water bottle. IF they have a bat and helmet, they are welcome to bring those too.

The registration fee covers equipment, instructor costs, insurance, facility permits and administrative expenses, as well as contributing to the Leaside Baseball Financial Assistance and capital improvement programs.


Financial Assistance

The Leaside Baseball Association provides an opportunity for players in Leaside and the surrounding community to develop their skills and passion for baseball by offering a wide spectrum of quality baseball programming. To make this instruction accessible to all, we are proud to offer a financial assistance program. Leaside Baseball is committed to an equitable baseball experience for all of our families.

If you would like your child(ren) to participate in our programming and wish to seek financial assistance, please apply to our Playball Financial Assistance fund. All information remains confidential.


Rep Players

We do not accept players who are currently on a rep team in Leaside or elsewhere in Toronto due to limited space in our program and the development offered through rep team practice activities. Players who have previously played rep baseball are eligible to play.
