The Mercury Tribune has had five owners and eight publishers since it began.

It employs carriers to deliver the paper and advertisements with it.

Torstar bought the newspaper from Southam in 2004 and it is now part of the Metroland Media Group which includes regional sister daily newspaper the Waterloo Region Record (Kitchener, Cambridge and Waterloo), as well as a group of weekly newspapers.

The paper is distributed free of charge, and is supported through donation drives and advertisements.
