The Lightning forward has donated $150 for every point he recorded this season to initiatives supporting mental health.
Paul, who will earn an average of $3.15million under his new contract, had five goals and four assists in his first playoff action.
While he wasn’t part of the first two Stanley Cup wins for the Tampa Bay Lightning, Nick Paul has fit in quickly along the quest for a three-peat.
As part of the deal, the Senators will retain 44.5 per cent of Paul's remaining salary for the 2021-22 season.
