Toronto District School Board

The Toronto District School Board and Toronto Catholic District School Board are experiencing school bus delays. In particular, parents of students who use Attridge Transportation, Wheelchair Accessible Transit or Sharp Bus Lines should expect significant delays and the possibility that some buses may not be running due to an unanticipated bus driver shortage. We are working to fix this issue as soon as possible.

Sir Alexander Mackenzie Senior Public School (GR. 07-08)

Today a Learner, Tomorrow a Leader

Sir Alexander Mackenzie Sr. P.S. (SAM) officially opened on January 20, 1972. Our school name honours a man who demonstrated integrity and perseverance while exploring his way across Canada. Sir Alexander Mackenzie was born in Scotland. He was a fur trader and the first white man to cross North America north of Mexico, charting and exploring huge expanses of Canada. One of the rivers he explored, the Mackenzie River, bears his name. His voyages were published in 1801, he was knighted in 1802 and in 1804, he was elected to the House of Assembly of Lower Canada. SAM is located in Agincourt and has a history of responding to the changing needs of its community. SAM is a dynamic, multicultural school with a host of opportunities for students.
