Looks to be the foul territory area beside the Blue Jays bullpen - you can see the elevated bullpen in the bottom right of the photo.Looks to be the home plate area? The 100 level seats used to be on two giant rails that allowed them to split open for football mode. Those seats are gone and the rail mechanism is likely being dug up as well.
Also those new seats would need footings to be dug. And the premium spaces behind the dugouts and home plate need to be built as well
Just my guess - extending some infrastructure to accommodate the new clubs underneath the new 100 level, and what ever team facility upgrades are being done.
