Stolarz made 26 saves in Wednesday's 1-0 loss to the Canadiens.
The 30-year-old played well in his Maple Leafs debut -- the only puck to get past him came on a Cole Caufield one-timer on the power play -- but Sam Montembeault stood on his head in the other crease. Stolarz was expected to back up Joseph Woll (lower body) this season, but given the latter's sketchy injury history and the fact that he's already on the shelf, that's still likely to lead to a career-high workload in 2024-25.
