Westmount High School

What a weekend for WHS athlete Tristan Xavier Chiasson (Sec 4)! 🏃‍♂️⚔️

Representing Westmount High School as the only WHS athlete selected to the GMAA team, Tristan competed at the provincial RSEQ Track & Field Championships in Sherbrooke and delivered outstanding performances against the best athletes in Québec.

Tristan ran an impressive 52.90 in the 400m, earning 9th place in the province, and posted a time of 24.02 in the 200m, tying for 13th in a tightly contested three-way finish. Despite an arm injury that prevented him from competing in javelin, Tristan showed incredible determination throughout the weekend.

He was also selected to run the anchor leg of the 4x400m relay, helping his team finish 11th in Québec with a time of 3:51.75.

Congratulations, Tristan! Your hard work, perseverance, and sportsmanship make the entire WHS community proud.

Go Knights Go! ⚔️💜🤍

Today, the WHS community gathered for a special Leadership Assembly in honour of Mr. Kosow as he prepares to retire after 26 years of inspiring generations of students.

For more than two decades, the “Leadership Guru” has been a source of positivity, motivation, and wisdom for over 7,000 WHS students. His lessons went far beyond the classroom. Whether it was making your bed, recognizing your lollipop moments, or finding your broom, Mr. Kosow challenged students to be leaders, to serve others, and to make a difference in the world around them.

The assembly was moving, emotional, and a fitting tribute to a teacher whose impact on our school community is impossible to measure. There were very few dry eyes in the house as students, staff, alumni, and friends reflected on the countless lives he has touched.

Thank you, Mr. Kosow, for your passion, your guidance, and your unwavering belief in the potential of every student who walked through your classroom doors. Your legacy will continue to inspire WHS students for years to come.

We wish you all the best on your next adventure!

✉️🍕 Today, Ms. B’s Grade 7 class celebrated the culmination of their year-long pen pal project in the library!

Throughout the year, students and members of our local community exchanged six letters, building meaningful connections through the art of letter writing. Today, they finally had the opportunity to meet in person, sharing pizza, games, and great conversations.

What a wonderful way to bring together different generations and celebrate the relationships that were formed over the course of the school year. Thank you to Ms. B, Ms. Samantha and everyone who participated and helped make this special project such a success! ✉️❤️🍕

🎮 Yesterday, Ms. Outland and her students enjoyed an incredible visit to the headquarters of Ubisoft in Montreal after winning a special class draw!

Students had the opportunity to learn about the video game industry, explore career opportunities, and ask some excellent questions throughout the tour.

The biggest laugh of the day came when they were asked to place their cell phones in Yondr pouches before the tour began. As a phone-free school, WHS students were already pros!

Thank you to Ubisoft for a wonderful experience and for educating our students with a behind-the-scenes look at one of Montreal’s most innovative industries. 🎮✨

What an incredible evening of music at Westmount High School last Wednesday as our WHS Jazz Band shared the stage with the Quebec Youth Wind Ensemble!

From the timeless works of Gustav Holst to the modern music of Lin-Manuel Miranda, the audience was treated to a wonderful showcase of talent, dedication, and musicianship. Our student performers represented WHS with pride and delivered an outstanding performance.

Congratulations to Mr. Cox and the entire Music Department for organizing such a memorable concert, and thank you to everyone who attended and supported our young musicians.
