A three-phase renovation of the arena began in 2017 and was completed in 2019, with all building works being done in the hockey offseason to minimize schedule disruption. The first phase was largely composed of engineering upgrades (new lighting, sound, HVAC, and ice plant), improved IT infrastructure including free Wi-Fi for patrons, and rebuilt dressing rooms, as well as a new scoreboard and replacement of some lower-tier seating on the west end (where the Blues shoot twice) with "theater boxes". Phase two saw the replacement of all upper-tier seats, along with "theater boxes" being added to the east end, and a rebuilt lower-tier concourse with new club areas for premium ticketholders as well as a beer garden opening onto 14th Street. The third and final phase included the replacement of lower-tier seats and renovations to private boxes.
