Initially, he was meant to be traded to the Calgary Flames, however, they were on his no-trade list. Despite this, then general manager Kyle Dubas attempted to capitalize on his fragile family situation, with a new child just days away and tried to pressure him into a deal.
The process reportedly took the following steps: Kadri was called in for a meeting with Kyle Dubas and other Maple Leafs management, told he was part of the future plans, and essentially that he and his wife, who was nine months pregnant, would be staying in Toronto. Out of nowhere, however, Kadri began getting calls and messages from players and executives in the Calgary Flames organization, trying to convince him to waive his trade protection.
Kadri was never told by the Maple Leafs that he was being shopped in the first place and thus used his contractual right to veto the trade. This caused tension between Kadri and his teammates and eventually was moved to the Colorado Avalanche. He would go on to win a cup there, cementing himself in NHL history with his name engraved on Lord Stanley.
