$5
The polymer $5 is blue and carries a portrait of Sir Wilfrid Laurier, with the Canadarm2 and Dextre on the back.
In the large window, the small metallic portrait must match Laurier and the metallic building is the Parliament Buildings. Tilt to confirm both change colour.
Shine a single point of light through the frosted maple leaf to reveal a hidden 5.
$10
The current $10, issued in 2018, is vertical rather than horizontal and carries a portrait of Viola Desmond, with the Canadian Museum for Human Rights on the back. It is purple.
Because the note is vertical, the window and its elements run in a different arrangement from the other denominations. This is the design and not a sign of tampering.
The horizontal polymer $10 from the earlier Frontier series, which carries a portrait of Sir John A. Macdonald and a train on the back, also remains legal tender.
Shine a single point of light through the frosted maple leaf to reveal a hidden 10.
$20
The polymer $20 is green and carries a portrait of Queen Elizabeth II, with the Canadian National Vimy Memorial on the back.
In the large window, the small metallic portrait must match the Queen and the metallic building is the Parliament Buildings. Tilt to check both shift colour.
Shine a single point of light through the frosted maple leaf to reveal a hidden 20. The $20 is the note Canadian ATMs dispense most, so it is the one to know best.
$50
The polymer $50 is red and carries a portrait of William Lyon Mackenzie King, with the research icebreaker CCGS Amundsen on the back.
Check that the metallic portrait in the window matches Mackenzie King, and reveal a hidden 50 in the frosted maple leaf under a single light source.
$100
The polymer $100 is brown and carries a portrait of Sir Robert Borden, with medical research imagery on the back.
Check that the metallic portrait in the window matches Borden, tilt to confirm the colour shift on the portrait and building, and reveal a hidden 100 in the frosted maple leaf.
As the highest circulating denomination it is the one most worth running every check on, including the raised ink on the shoulders and the transparent text in the window.
