I'm afraid they do.
My Canadian tables show that 1 quart = 1.14 litres (note spelling), thus a pint = 0.570 litres.

Which only goes to show that one can get drunker quicker in Imperial than American measure.

More digression-
I noted on my last cruise that knots were used for speed (a Dutch line). My Canadian table shows one knot (one nautical mile) equals 1.15266 statute miles.
Since 1959, officially in the U. S., a nautical mile = 6076.115 feet or 1852 meters (Webster's Collegiate Dictionary).
Now if one multiplies 1.15266 by 5280 (feet in a mile) that = 6086.0448 feet. Don't quite equal out, eh?
There also is an entry that a nautical mile is a British unit = to 6080 feet (1853.2 meters).
As the song says, "let's call the whole thing off."
