It could be a worn or damaged valve, OR it could be some schmutz got stuck in the valve causing it to not fully close. Try rapid opening and closing to see if the seal reseals. Try turning off the pressure and drain down the line a bit to see if that dislodges any gunk. You can even shut off the water, disconnect the line and blow some low pressure air into the toilet while working the valve to see if that helps.
A couple years back I had a sticking valve. I shut off the water, removed the line and squirted some liquid dishwashing soap into the inlet while opening and closing the valve. After reconnecting, no more stuck open valve (I did replace it anyways later that year as a precaution).
if those don't do it, you'll need to make a temp fix like MFL or gwalter suggested.
