Joan - thank you. Good question about the people on our money. Please bear with me.
In summary:
$ 5 - Sir Wilfred Laurier
$ 10 - Viola Desmond or Sir John A MacDonald
$ 20 - Queen Elizabeth II
$ 50 - W.L. Mackenzie King
$100 - Sir Robert L Borden
Most of the people are former Prime Ministers of Canada. Yes, the money is different colours. It's also plastic (!)
In detail:
Yes our bills are all different colours which is oh-so-helpful from a distance. For the US money I have to look close if it's a $1 or $10 since they are the same colour... but usually $1 are more tattered/well used. Also our bills are plastic (polymer) - not paper. And they have holograms and other anti-counterfeit measures. Reportedly it's working - the fakes are easier to spot.

- The $5 bill has Sir Wilfred Laurier (7th Prime Minister of Canada, 1841-1919,
https://en.wikipedia.org/wiki/Wilfrid_Laurier) on the front, and the CanadaArm on the back - a robotic arm on the space shuttle. (

- The $10 bill has Viola Desmond (Canadian civil rights and woman's rights activist, 1914-1965,
https://en.wikipedia.org/wiki/Viola_Desmond) on the front and the Canadian Museum of Human Rights in Winnipeg, Manitoba (
https://humanrights.ca/) on the back. This bill design seems to have won an international banknote of the year award (
https://www.cbc.ca/news/canada/nova...ll-wins-banknote-design-competition-1.5116527 - who knew that was even a thing?) in 2019; the note may have become legal tender in 2018.
- Some $10 bills have Sir John A MacDonald on the front (1st Prime Minister of Canada
https://en.wikipedia.org/wiki/John_A._Macdonald) and the "Canadian" train on the back (maybe this one?
https://canadarail.ca/) . The bill I consulted was issued in 2013.
- The $20 bill has Queen Elizabeth on the front and the Canadian National Vimy Memorial (in France!
https://www.veterans.gc.ca/eng/remembrance/memorials/vimy) statue on the back.
- The $50 bill has W.L. Mackenzie King (10th Prime Minister of Canada, 1874-1950,
https://en.wikipedia.org/wiki/William_Lyon_Mackenzie_King) on the front and a Canadian Coast Guard Ship Amundsen on the back. This was an icebreaker in service 1979-1996 (
https://en.wikipedia.org/wiki/CCGS_Amundsen)
- The $100 bill I don't see often (I'm not imagining it - wikipedia says "It is the highest-valued and least-circulated of the notes since the $1000 note was gradually removed from circulation starting in 2000."
https://en.wikipedia.org/wiki/Canadian_one-hundred-dollar_note) It has Sir Robert L Borden (8th Prime Minister of Canada, 1854-1937,
https://en.wikipedia.org/wiki/Robert_Borden) on the front and a woman with a microscope on the back with a bottle of Insulin depicting the discovery of insulin .
Phew - I feel I wrote an essay. I'll return with more comments later.
