Canada Day has no meaning.
Sure it does. It means the same thing that July 1st has always meant. It's a holiday.

It's silly to argue over what July 1st should be called. Canada is 150 years old this year. The birthday is important. What you call the day, isn't.
How Did Dominion Day Become Canada Day?
At 4 o'clock on Friday, July 9, 1982, the House of Commons was almost empty.
The 13 parliamentarians taking up space in the 282-seat chamber were, by most accounts, half asleep as they began Private Members' Hour. But then one of the more wakeful Liberals noticed the Tory MPs were slow to arrive in the chamber.
Someone -- exactly who has never been firmly identified -- remembered
Bill C-201, a private member's bill from Hal Herbert, the Liberal MP from Vaudreuil, that
had been gathering dust ever since it had received first reading in May of 1980. "An Act to Amend the Holidays Act" proposed to change the name of the July 1 national holiday from "Dominion Day" to "Canada Day."
The whole process took five minutes. The MPs celebrated by declaring an early end to session at 4:05 p.m. "It is only appropriate that, in celebrating our new holiday called Canada Day, we should at least take a holiday of 55 minutes this afternoon," said New Democrat Mark Rose.
