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.
