The 1982-1996 Canadian pennies are thinner than the 1981 and earlier pennies. They should weigh 2.5 grams (compared to 3.24 grams for 1979 and earlier, 2.8 grams for 1980-81). Since they are the same diameter, it would follow that they should be thinner. Also, they are 12-sided and this was apparently done to help the blind identify the coin. It doesn't sound like you have anything out of the ordinary there.
