Niverville Collegiate south of Winnipeg suffered significant damage on June 13 after two people allegedly vandalized the school.
Twenty-nine windows were broken and two school buses were damaged in the parking lot at around 2:30 a.m.
Two males fleeing from the scene were eventually arrested.
A 26-year-old man from the RM of Ritchot, and a 16-year-old boy from Emerson, Manitoba have each been charged with mischief over $5,000.
They will appear in St. Pierre-Jolys on August 11.
RCMP say the two did not gain access to the inside of the school.
