===Canada===
Canada formerly used a US-style ACTS coin phone system with a tone pair which would beep once for a nickel, twice for a dime and five times on receiving a quarter. These phones did not accept $1 coins (or the later $2 coin) and disappeared with the roll-out of [[Nortel payphones#Millennium|Nortel Millennium]] payphones in the 1990s. The Millennium sets do not use ACTS in-band signalling tones as all coin-handling is automated in the phone itself.
