There's a LOT of work still to be done, and in the grand scheme of equality this is actually a pretty small victory. But a victory is a victory and worth celebrating. There'll be a lot of court cases about the issues Yuri Girl 1001 raised, with this decision being cited as precedent, and there are still many, many other rights issues (like the fact that you can still be fired for your orientation in most places, trans rights have barely been touched, etc.) that still need to be addressed.
I'm still willing to look at this as a win, and as an Official Canadian I'd like to welcome y'all to the civilized world.
