A little of both...it sheds water, at the same time there is a small amount of absorption which swells the fibers, enhancing the waterproof qualities.
I have deer hunted out of canvas wall tents for years, and the only time I've experienced any leakage was during a multi day rain event of Biblical proportions. The leakage was slight...barely remarkable. I've never treated my canvas.
