It's a Chippewean 16. This model hasn't been made for years - I bought it at least 20 years ago. It's made of what was then called Oltanar and is now called Royalex; which is an ABS/Foam/ABS laminate. Many canoes have a raised strip down the center that aids in tracking, but this one has a smooth bottom and is difficult to paddle straight, especially when the wind is blowing. However, it is very manuverable and the product literature from the time it was purchased shows it running whitewater.
