For #1 - yes lossy

A better test would not have a 'tolerance' for passing and failing.
I see Firefox, Safari and IE9 all fail, though they get fail because the tolerance is too high.

For #2 http://test.w3.org/html/tests/submission/PhilipTaylor/canvas/toDataURL.jpeg.quality.notnumber.html

You mean lossy images, right? I'm not sure exactly what your bug report is. You think we can't have tests that check for approximate values, or something else?

Is this the right URL for this test? I can't see the problem you allude to here.
