Ottawa Public Health is investigating after a report the same pesticide used at Charles H. Hulse Public School was also used at the Adult High School.

A report of pesticide-related symptoms at the Adult High School was brought to Ottawa Public Health’s attention Wednesday by the Ottawa Carleton District School Board. One complaint was filed, according to Ottawa Public Health.

A public health investigator is on scene. The investigator will work to determine whether the same pesticide was applied, how it was applied and how many people may have been affected.

The Ministry of Labour and the Ministry of the Environment are also involved.

The school’s principal, Kevin Bush, would not comment.

The reports come just a few days after students at Charles H. Hulse Public School were relocated to another building after a harmful pesticide was used nearly two weeks ago.

The Ottawa Carleton District School Board closed the elementary school on Friday after 31 students went home sick. After cleaning and ventilation this past weekend, the school was supposed to re-open Tuesday.

But on Monday, staff that went in to the school to set the classrooms back up noticed the pesticide smell was returning. A few started to have symptoms again.

The school board sent out a notice Tuesday afternoon that as of Wednesday morning, students and staff at the school will be relocated to Parkwood Hills Public School building at 60 Tiverton Drive, which is currently vacant.
