Will LH/ANA check my bags through to YYZ if my AC flight is on a separate ticket?

I’ve got TYO–MUC on ANA and then MUC–ORD on Lufthansa, all on one booking. Then my plans changed and I added a separate ORD–YYZ AC ticket. I’ve got 2.5 hours in Chicago before that last leg.

Just trying to figure out if AC can merge it or if I’m stuck grabbing my bags in ORD and rechecking before heading to Toronto
