Senior Prank

Relay for Life

GSS has hosted five Relay for Life events for the Canadian Cancer Society in the past ten years. In 2011, GSS hosted its most successful fundraiser, accumulated over $90,000 for the Canadian Cancer Society. The secondary school hosts the student-organized event every two years.

Planned closure

On March 28, 2017, the District School Board of Niagara voted in favour of a motion to close three high schools, including Grimsby Secondary School, in favour of a single large high school to be constructed at a yet-to-be-determined location. Under the current plan, Grimsby Secondary School will close in 2020 following the 2019–2020 school year, and the new amalgamated high school will open in September 2020.

Opposition to planned closure

Many groups have been vocal in opposing the planned closure of Grimsby Secondary School. The Town of Grimsby, as well as the Town of Lincoln, have both passed motions voicing opposition. Niagara West-Glanbrook Member of Provincial Parliament Sam Oosterhoff, himself a recent high school graduate, has also voiced opposition to the amalgamation plans, and has spoken in the Ontario Legislative Assembly in favour of a moratorium on school closures. On Wednesday, March 29, students at South Lincoln High School walked out of class in protest over the closure and amalgamation plans.
