[1] The initial museum site was situated on a 92-acre parcel of land, next to Kelso Conservation Area on what was then known as West Town Line but was renamed to Tremaine Road in 1967.

[6] A call for tenders was announced in March 1974 by Halton East MPP James Snow for stage two of the new agricultural museum.

The second phase completed construction of the 20,000 square foot, one-storey museum building designed by Oakville architects Hallford and Wilson.

[12] Stage three of the development envisioned the installation of pioneer farmsteads which would be restored on site, with various regions, time periods and types of Ontario agriculture represented.

[13] In 1977, the Museum had a permanent staff of seven, including the general manager Bob Carbert, but Carbert said in a speech to the Milton Historical Society that year that he anticipated that staffing level was only one-third of the staff he required in order to continue acquiring and restoring artifacts, as well as serving the museum's public visitors.

[16] On April 1, 1997, the Ontario Government ceased its operation of the site, and it was announced in November 1997 that the museum would essentially close, with the anticipation that no public program would be offered in 1998.

The board's initial concern was to "stop and get control of the operation" with an eye to self-sufficiency and financial sustainability through the hosting of events, admission revenue, school visits, group tours and facility rentals.
