Umpire Clinic Registration Process:

FIRSTRegister as a NTBA Umpire:

If this is your first season as a NTBA Umpire, please follow the steps below.  If you are already registered in Horizon, you can skip the first registration process but please update your Horizon profile with your 2023 umpire level.

SECOND:  Register for an Ump Camp with Baseball Ontario:

Level 1 and 2 umpires will register through Baseball Ontario, and fee payment will be made through the local association when you attend the Umpire Camp.  There are 3 components to certification:

  1. Complete a virtual Umpire Learning Course comprised of a series of independent learning modules. The total expected time for the course is 2 hours.
  2. Attend a 4 hour in-person, locally hosted Umpire Camp.
  3. Attend a 1 hour in-person, NTBA Local Rules Infoshare


Log in credentials to the previous umpire profile site are no longer effective.  All umpires (new and returning) must register for a new profile using OnDeck here.  For your profile, select your 2023 Ump Level.

The OBA is aware of a known glitch in the system and are working with the developer to resolve.  For the short term, if you are not 13 years old when you register, enter your month and day of birth and “1924” for year of birth. That will allow your profile to be created.  The OBA will send an email to the address associated with the account when the capability to enter the correct birth year is enabled.

Once you have set up your profile, click on your name in the top right corner, then click “my account”, then choose “certifications” from the left menu, then choose the corresponding certification from Available Certifications.

Component #1 - Completing the modules in the Available Certifications completes the 1st component in your certification.

Component #2 - The last item in the Umpire Certification box is Umpire Camp, click on the “View Events” box. NTBA will be hosting 4 Umpire Camps on April 23, held at Northern Secondary School (2 Umpire Camps starting at 8:30 and 2 Umpire Camps starting at 1:00).  Please register for one of the Umpire Camps.   The NTBA hosted Umpire Camps are open for  registration.   There are limited spots so do not delay registering!  NT umpires do not need to attend one of the NTBA hosted Umpire Camps, you can attend any Umpire Camp.  The clinicians are all OBA certified.

Component #3 – Attend a NTBA Local Rules infoshare, held on April 23 at Northern Secondary School.  There will be one held in the morning (10:30AM to 11:30PM) and one in the afternoon (1:30PM to 2:30PM), to accommodate umpires attending the Umpire Camps.  Please register for the Local Rules Sessions, here is the link.
