In 2004, the Leduc Community Arts Foundation, along with the City of Leduc and Black Gold Regional Schools undertook yet another renovation; this time to increase seating capacity to the current 460. Numerous sponsors were brought on-board, most notably Maclab Enterprises, for whom the venue is named. The idea was to do more than simply expand the theatre; people wanted an increased usage by community groups, and to have artists presented from outside the community. This new facility opened in November 2005.
The Maclab Centre Administrative Council, comprised of members of Black Gold Regional Schools and the City of Leduc, was formed with the mandate of managing the space independently of the City and the School Board. A full-time Theatre Manager was hired in 2006 and 2007/2008 saw the first performance series programmed in the space. To accommodate the increased need for technical support, the first full-time Technical Director was hired in 2007.
Operation of the facility was transferred to the Maclab Centre for the Performing Arts Society in 2008, marking the first time the facility has been managed by an independent body.
After much discussion, operations were transitioned over to the City of Leduc in 2019.
