Toronto hates Florida because Toronto ain't Florida.
Florida actually wins things like the President's Trophy and the Prince of Wales Trophy.
The Leafs...never a President's Trophy...not a season even close. PoW trophy...55 plus years of zero successes, all early exits, no deep runs. Proven frauds they are, both historically and presently. Florida has accomplished more in 2 seasons than Toronto has in nearly 6 decades and they loathe you because they know they're inferior and unable to meet/beat your accomplishments. Truly they're the lesser team.
Heck, in Toronto's best Cinderella season, they were dominated by Montreal after taking a 3-1 series lead. They literally stood on the doorstep of playoff advancement and allowed their soft, weak, fragile and heartless core values to lose 3 straight games to end the series. Absolute losers.
