Mitch Marner was traded from the Toronto Maple Leafs to the Vegas Golden Knights. This trade was completed just before the start of the NHL free agency period in 2025, where Marner signed an eight-year contract extension worth $96 million with the Vegas Golden Knights. The trade involved the Maple Leafs receiving center Nicolas Roy in return. Marner, who had spent nine seasons with Toronto and was a top scorer, chose Vegas as his preferred destination. His new contract with Vegas ensures an average annual value of $12 million, and this move marked the end of his tenure with Toronto and the so-called "Core 4" of the Maple Leafs.
