Little actual physical money appears in episodes of Forever Knight, though paper transactions are often mentioned. In particular, when money is stolen, dollar amounts are usually mentioned.
Actual Canadian currency is seen in "Blind Faith", when Nick Knight pays Screed with a $100 bill for information about carouche activity in the Toronto region. However, this is the only episode in which a Canadian dollar bill of any size is seen.
Canadian banknotes are variously coloured, depending on the denomination. When Forever Knight was being made, the following were in common use:
- $2 (brick red)
- $5 (teal blue)
- $10 (purple)
- $20 (olive with touches of apricot)
- $50 (red with touches of green)
- $100 (brown).
At the time, there was also a $1000 bill, but it has since been discontinued. The $2 bill also no longer exists: in 1996, it was replaced with a $2 coin, sometimes called a "toonie". The old $1 bill (green) had similarly been replaced with a coin (the "loonie") back in 1987, before the series started.
The Canadian unit of currency is the dollar, which is subdivided into 100 cents. For small denominations of money, coins are used. All Canadian coins have the reigning monarch's head on the obverse ("heads") side, while the reverse ("tails") side has some other picture, which varies depending on the denomination of the coin and the date of issue. At the time Forever Knight was being made, Canada had the following coins in regular use:
- 1¢ ("penny") maple leaves on reverse
- 5¢ ("nickel") beaver on reverse
- 10¢ ("dime") Bluenose sailing vessel on reverse
- 25¢ ("quarter") caribou on reverse
- $1 coins ("loonie") loon on reverse
There is also a 50¢ coin ("fifty cent piece") with the Canadian coat of arms on its reverse, but it is rarely used. The penny is copper coloured, the loonie is brass coloured, and the other coins are silver coloured.
