In an email to Global News, SPS spokesperson Veronica Baker said the three schools were Pleasant Hill, Sutherland and Wâhkôhtowin.
Police were called immediately and all three schools enacted lockdown procedures.
A Saskatoon Police Service release said officers were responding to each of the locations and the public was asked to avoid the area.
An updated release said around 12:30 p.m., police received a 911 call reporting a person with a firearm approaching an elementary school in the 200 block of Avenue S South.
Police say patrol, school resource officers and on-duty tactical support unit officers responded.
“At 12:36 p.m. and 1:13 p.m., police received two additional 911 calls with similar reports of threats involving elementary schools in the 200 block of 111th Street and the 3500 block of John A. Macdonald Road, respectively,” the release stated.
Police say officers cleared each room and no threat was located.
Baker said once the schools were cleared by officers, the lockdowns were lifted.
Baker said all students and staff members were safe and classes had resumed.
“The safety of our students and staff members is our priority. The situation was handled quickly and effectively by both the school staff and the police. We are grateful to our students who listened to instructions and followed the practiced procedure,” Baker said.
Baker added each situation was treated as a serious incident and additional counsellors were brought in to provide support for any students who needed it.
Police continue to investigate these incidents and ask anyone with information to contact them at 306-975-8300 or Crime Stoppers at 1-800-222-8433.
