June is Pride Month!

Pride in Canada is celebrated during the month of June to commemorate the Stonewall Riots (USA) in 1969 and the Toronto Bathhouse Riots in 1981.  Canada decriminalized homosexuality in 1969, 1 day before the New York Stonewall Riots, and it wasn’t until 1973 that homosexuality was removed as a “disorder” from the Diagnostics and Statistics of mental disorders.  Pride month celebrates the freedoms we have gained in our country as well as reminding us that there is still work to be done for LGBTQ rights.  Centre Dufferin knows that diversity is one of our strengths and we celebrate Pride month in a variety of ways, including hosting a carnival and flying the rainbow Pride flag for the month of June.


Hair Off for Headwaters Raised $4 800!

On May 23rd, the 18th Annual Hair Off for Headwaters assembly took place. This event was organized by the Grade 12 Business Leadership class. Students purchased tickets to attend the assembly, which featured staff & students cutting or shaving their hair. There were also games and lots of door prizes that were generously donated by local businesses. Some teachers took a pie in the face because their class met their goal of contributing at least $100. In total, $4 800 will be donated to the Cancer Care (Oncology) Unit at Headwaters Hospital on behalf of our school. Overall, CDDHS has donated more than $156 000. Thank you to the brave students who cut their hair and worked hard to raise money, and to everyone else who supported our event!
