What gives 'The Tenors' the right to send a political message through a country's National Anthem?? #MLBAllStarGame #Canada

Tenors butchering our Canadian national anthem is an insult to our great land. The anthem represents all of us.

WHAT THE FLIP was that with the CANADIAN anthem? Can you IMAGINE if anyone changed the Star Spangled Banner? WHAT WERE THE TENORS THINKING?

"And now, please welcome the Tenors, to somehow insult the black community and ruin the Canadian anthem at the same time. Play ball!"

Why The Tenors chose to re-write the Canadian national anthem is beyond me. I'm speechless. #ASG

The Tenors' #lonewolf thought O Canada "All Lives Matter" change would "bring us all together." It did. To bash him. https://t.co/Y56FPi2ByL

How about not changing the lyrics to the Canadian anthem to make a racist and ignorant statement. That's always an option #tenors

How dare the "Tenors" hijack the Canadian national anthem for their personal agenda. Classless, egotistical idiots. 🇨🇦⚾️ #AllStarGame
