Annual General Meeting

We are always on the search for more volunteers for the upcoming season though, so feel free to get in touch if you want to contribute!

Registration is Now Open

Update: on in-person session scheduled for March 21 is cancelled due to the closure of Harrow Howell arena and the mandate by Baseball Ontario to cancel all in-person activities. At this time, we will not be holding an in-person registration session. Please contact us if any assistance is needed to register manually, otherwise please do not hesitate to register online using Paypal if available or by sending in a cheque noted on our registration page.


Registration for mixed houseleague, girls softball and our rep program is now available on-line as we get ready to take on another great baseball season. Though we encourage our members to register on-line, for those who have the inability or prefer not to use the internet to register, we will also be offering in-person registration on March 21 at Harry Howell Arena from 9am - 2pm (tentative due to the current health concerns). If you have the ability to register on-line but do not want to use our on-line payment system, you can register without paying and drop off your payment at our in-person session. This would be highly appreciated to save our volunteers valuable time and effort. Mailing in a cheque is also always an option and the registration form and mailing address is available under the registration tab on the website. Note that the registration cutoff this year for earlybird fees is April 10, so ensure that you register in time to take advantage. Fees will increase $50 after this date. Registration ends May 31. If you have any questions, including what tentative days each division plays, feel free to browse our FAQ section under our Member Info menu or email us through our Contact Us section.
