The Simpsons part of the logo was dropped in 1972 and it became known as just Sears (though it was still legally known as Simpsons-Sears, and many stores continued to be branded as such, until 1984).
A new font style has changed having it in all uppercase letters.
Same as the previous logo but with the red maple leaf.
The letters changed from all uppercase letters to lowercase letters leaving the capital 'S' intact.
Similar to the logo used for 2000-2004.
Sears Canada declared bankruptcy in 2017 and started closing stores. All Sears Canada stores closed on January 14, 2018.
