No there isn't one place. I did a web search all over (about 50 effective links). Wilson is getting the top pay in Toronto at about $1.7mil. Rookie HCs are generally around $600k. Quenneville was looking for ~$1mil when interviewed for the Sharks job. Historical win/loss record is related to pay. GMs make more than coaches.
On a side note, top NCAA HCs are paid over $200k base pay with bonuses that can take them over $400k. This pay level was set so as to prevent NHL teams from poaching them for anything but HC jobs. The inference is that NHL ACs and AHL HCs make less.
