Final answer:
The player who led the Toronto Maple Leafs in points during the 1989-90 NHL season with 95 points was Wendel Clark.
Step-by-step explanation:
The player who led the Toronto Maple Leafs in points during the 1989-90 NHL season with 95 points was Wendel Clark. Neither Doug Gilmour, Mats Sundin, nor Darryl Sittler accomplished this feat that year. In fact, it wasn't until the 1991-92 season that Doug Gilmour joined the Leafs, and Mats Sundin didn't join until the 1994-95 season. Darryl Sittler, on the other hand, had long been retired from the Leafs by that point.
