Originally designed primarily to house baseball (with football being a secondary consideration) the stadium was converted to a football-only facility in 1966.

When heavy rain turned the field to mud, the team was compelled to relocate games to other venues in the city, including the RCMP barracks.

Late-season games were frequently played in dust bowl conditions, and heavy rain turned it into a mud bath.

[6] When the stadium was first built, minor league baseball was a relatively popular spectator sport in much of North America, including Western Canada.

In 1966, a second permanent grandstand was constructed, significantly expanding capacity for Roughriders games while also effectively converting Taylor Field to a football-only stadium.

"When I first saw the stadium in Regina (in 1963), it looked like a farmer had built it, you know, like they'd just added on a few pieces here and there and half of the dressing room was dirt floor, where us rookies got to be.

[7] In 2006, a VIP deck and stands were put in place in the south endzone, allowing the football club to host its corporate game day sponsors.

[5][6][8] On July 31, 2008, the Roughriders announced that temporary seats would be added to the stadium due to high demand for tickets—the team had sold out every home game for the 2008 season.

[9] With tickets in high demand coming off their Grey Cup season, an extra 2,145 seats were added, bringing the capacity to 30,945.

Following the 2008 West Semi-Final game on November 8, 2008 against the BC Lions, the temporary seats were taken down, putting the capacity back to the original number of 28,800.

[11] On February 24, 2012, the Roughriders announced a $14 million renovation plan known as the "Legacy Project" to prepare the stadium for hosting the 101st Grey Cup.

Riders chairman Roger Brandvold was quoted as saying "Replacing Mosaic Stadium still remains our top priority, but certain upgrades needed to be made to get us through the next few years and especially the 2013 Grey Cup".

This concert, however, was cancelled due to the injuries that Steven Tyler sustained after falling off the stage in Sturgis, South Dakota.
