Yeah, I read an article once on that Canada program, probably when they were talking about free agents and the disadvantages that some Canada cities have enticing players to sign because of taxes vs signing with Tampa or Florida (or Dallas or Vegas).
Not that NHL superstars are not very well paid, but the whole Cap/Escrow process and taxes does take a rather large bite out of their salary and bonuses. They still do rather well of course. But the NHL really won a major victory with the cap/escrow/profit sharing system contained in the past 2 CBAs. It appears this new CBA extension that should be finalized soon will help relieve some of the pain the players will face for at least a couple of years with Covid-19 revenues almost certainly plunging.
