I guess they were worried it had fallen too far down the most expensive stadium rankings.

From their wikipedia

In mid-November 2006, the stadium's costs were finally paid in full, more than 30 years after it opened.[7] The total expenditure (including repairs, renovations, construction, interest, and inflation) amounted to C$1.61 billion, making it—at the time all costs were paid off—the second most expensive stadium built (after Wembley Stadium in London).[18] Despite initial plans to complete payment in October 2006, an indoor smoking ban introduced in May 2006 curtailed the revenue gathered by the tobacco tax.[7] By 2014, the stadium's expense ranking had fallen to fifth, with the construction of costlier venues like MetLife Stadium, AT&T Stadium, and the new Yankee Stadium. Perceived by many to be a white elephant, the stadium has also been dubbed The Big Owe due to its astronomical cost.
