Okay, I found a website for the Canadian bills, too, if anyone is interested:
http://www.wallis.com/cdn_bills/
Then you can see just how colourful they are.
And for more imagery, I can now tell you who's on them:
$5 - Wilfred Laurier - 2nd prime minister (I think), and a bird (belted kingfisher) on the reverse side
$10 - John A. Macdonald - 1st prime minister, and peacekeeping/Remembrance Day stuff on the back (this is brand new, came out last month) (the old one had an osprey on the back)
$20 - the Queen, plus a loon on the back
$50 - William Lyon Mackenzie King (prime minister during WW II, I think) plus a snowy owl on the back
$100 - Sir Robert Borden (prime minister, don't remember when), plus a Canada goose on the back

They have just stopped making $1000 bills. These had the Queen on them. (I had a bath towel modelled after one.) All the bills also have pieces of the Parliament Buildings on the front. Funny about all the animals - I had noticed the animal theme on the coins but I hadn't really noticed it so much on the bills until I wrote up this description. As I recall, the $2 bill had robins on the back, before it was replaced by the coin. I guess it was a bird series.
