Ok well the white part is the urates. The urate is the bi- product of the kidneys. Generally as long as it is white its normal. The watery part that you are describing is the urine. The thing that is concerning though is the lack of stool in the droppings. The stool is the solid part, which is usually a brownish to greenish color. The issue is that there should be some stool every time the bird defecates. So if you aren't seeing any stool this can be an indications of more serious underlining issues such as a GI issue, or decreased appetite ( which could be caused by something major.
Most species of birds mask there clinical signs. What this means is that a bird will not show any signs of illness until they are nearly clinical. To make a comparison a human with a upper respiratory infection will show physical signs of illness such as red puffy eyes, scratchy throat, etc. A bird on the other hand will not show any of these physical signs. This is often referred to as flock behavior. In nature birds that show any signs of illness are segregated from the majority of the flock. The ill bird is not allowed to eat, drink, and often forced to keep a distance. This segregation usually ultimately leads to the bird being picked of by a predator. And this behavior generally applies to all species of domesticated birds. One must also understand that even though the bird is a solitary bird, they still will consider the owner to be a member of the flock.
My reccomendation would be to take him to a qualified avian vet. He should be able to wait till Monday. But I would monitor him very closely meanwhile. Look to make sure he is eating, drinking, vocalizing, no nasal or oral discharge, and is breathing clear.
Also most likely you take him to the vet, they will keep the stress on him to a minimum. Canaries stress out very easily during restraint and illness.
Lastly, make sure you locate a qualified avian vet. If you need help locating one let me know. I will be more then glad to help you find one.
Well good luck
