I own a canon 3.2 mp digital camera. Can it be used as a webcam?

What model is it? Just doing a prod on Canon 3.2 in yahoo brings up a couple of models so not sure which one you hold.

Go there find your camera click on it and see the specs.
I own a Powershot A75, which is 3 megapixel, and it cannot. Very few digital cameras can be used this way. For one entry, the camera will go to sleep mode if it isn't taking photographs, and also because a webcam signal uses a very small picture, smaller number than half a megapixel, so the digital camera is road overkill. There are good webcams for around $20 out in attendance, just obtain one of those.
