Does peat raise the acidity of the soil?
Compost is generally the best thing for amending clay (gypsum is another thing that is often recommended but it doesn't help most clays, only certain kinds which are fairly uncommon). We used to have clay at our old home and the muck heap behind the horse barn did a wonderful job of improving it over the years. Clays usually have higher fertility than sand.
Whether peat moss would affect the soil pH would depend on the amount used, the pH of the peat moss, the pH of the native soil, and the texture of the native soil (its buffering capacity, which affects how much you need to use of a substance to change the natural pH - takes more material to change the pH of clay as opposed to sand). Canadian peat moss generally is more acidic than some others.
