As per all responses, they are correct. The only advantage to taking Canadian dollars is, of course, economic reasons, but the Canadian dollar is more or less at par with the DR peso. e.g. $1.00 Cdn = 9.8 pesos, therefore, you should be able to do the math on the 10's, making for less confusion and less headaches that would come with trying to calculate the peso to US$ to CDN$. So when doing your math when making a purchase, lets say in a disco buying a beer for 350 peso - well then you know you are paying appox $3.50 Cdn. When buying dinner for 2000 peso - well then it is appox $20.00 Cdn. I've been to the DR several times and don't want to spend alot of time worrying about conversion of money. Canadian funds are excepted almost everywhere, and there are banking machines all around the tourist areas, that way you don't need to carry alot of cash. One thing to remember, you will need $10.00 US for departure fees. Have fun, relax and try to leave all your stress and headaches here in the cold.
