October is Islamic Heritage Month

Islamic Heritage Month (IHM) is recognized at the TDSB during the month of October, with exciting activities and learning opportunities for students, staff and community members across our system. The IHM theme is Reflect. Celebrate. Learn, and this theme will continue to resonate in the educational opportunities currently being planned throughout the 2019-2020 school year.

To kick off this year’s TDSB IHM celebrations, please join us for a very special evening:

Dear parents/guardians,

We have just been informed that due to a significant production issue with our vendor, Premier Agendas, there will be a delay in the delivery of our school's student planners. This production issue has impacted the delivery of planners across the TDSB and across the province. While we can't confirm exactly when our school will receive our shipment of planners, we have been told by Premier Agendas that all schools will receive their planners by the end of September.

As we await our shipment of planners, attached are electronic versions of the school-specific information contained in the planners, as well as TDSB common pages. The TDSB common pages contain information about the Board’s homework policy, severe weather guidelines, code of online conduct, and more.

Thank you for your understanding as we work through this issue. Please let me know if you have any questions.

Parent Testimonial

"I am a mother of two boys who both attended Thistletown Collegiate High School.

My name is Cindy Torrison, I work for a family Ad Specialty Company called Comda Advertising Connections I am currently the Accounting Supervisor with many other titles.

Both my boy’s struggled getting through high school and so did I. I didn’t want them to go through what I did when I was in school as I did not have much support from my parents or my school.  My son’s both received tremendous support from the staff at TCI especially the Guidance Department.

I would kept reminding myself and my boy’s that there is a light at the end of the tunnel and it is just over the horizon and that we will make it there.  I was a very involved parent and I believe that helped my boys keep pushing forward.

All I can say is “stay the course” you will win with TCI, the teachers, guidance department and all staff are there to see that it happens.  It happened for my boys they both have successful careers and have grown up to be upstanding men.

Thank you TCI for your support and caring staff"
