New Registrations

If you are interested in registering for the 2019-2020 school year, please contact the office for details.

In preparation for the school year 2019-2020, Holy Trinity High School will be providing Group Registration presentations for those families that wish to attend our school and are not already pre-registered from one of our feeder schools. 

If you wish to register your son or daughter for the following school year, and he/she currently attends a school other than St. James, St. Anne, St Martin de Porres, or Holy Redeemer, please contact Holy Trinity at 613-591-9955 and ask for registration instructions. An administrator will support you with this process as well as invite you and your child to attend one of our Group Registration presentations. These will take place at the following times:

For those students entering Grade 7 or 8 - April 16th at 8:30 am, in the Learning Commons

For those students entering Grades 9 - 12 - April 18th at 8:30 am, in the Learning Commons

We invite you to call as soon as possible in order to secure your seat at one of our Presentations. We look forward to seeing you and your child there!
