The quarter, short for quarter dollar, is a Canadian coin worth 25 cents or one-fourth of a Canadian dollar. It is a small, circular coin of silver colour. According to the Royal Canadian Mint, the official name for the coin is the 25-cent piece, but in practice it is usually called a "quarter", much like its American counterpart. In Canadian French, it is called a caribou or trente sous ("thirty sous", based on the old exchange rate).^[1][2] The coin is produced at the Royal Canadian Mint's facility in Winnipeg, Manitoba.

From 1920 until 1967 the quarter contained 0.15 troy ounces of silver—one quarter as much as the silver dollar (0.60 ozt), one half as much as the 50-cent piece, and 2+1⁄2 times more than the dime.

Ordinarily featuring a caribou,^[3] the quarter has the most commonly altered reverse in Canada and is the usual venue for commemorative issues.

In 2004, a quarter was issued in honour of Remembrance Day, featuring a corn poppy on the reverse, a traditional symbol in Canada of that day. This resulted in an international incident in which American military contractors unfamiliar with the coin's design believed these coins were outfitted with nanotechnology designed for espionage.^[5]

Since 2000, the RCM has been issuing colourized quarters on Canada Day with designs aimed to attract young collectors. As with other collector coins issued by the RCM, the Canada Day series coins are non-circulating legal tender.

• The 1906 Small Crown is valued in the thousands of dollars even for very poor conditions.
• 1936 marked two valuable variations, the Bar and the Dot, both trend for over $1,000 in uncirculated condition.
• The 1951 Low Relief was predominantly only made available in proof-like sets and have a mintage of around 500.
• The 1973 Large Bust is among the most desired Canadian Quarter. They sell for around $300 in Proof Like or Specimen condition and can sell in the thousands for high-end circulation strikes.
• The 1991 quarter had a low mintage, of 459,000
• The 1992 New Brunswick quarter has several rotated die versions, with the 180-degree rotation selling for between $100 and $200 in uncirculated condition.
• 1999 featured mule versions of the September and November quarters. These coins do not have the 25 CENTS mark on them, making them legal tender without face value. Either usually sells for over $10 depending on the condition of the coin. The Royal Canadian Mint estimates a combined mintage of 10,000 to 50,000 of the September and November mules.
• The 2000 Millennium Map mule. Highly sought after by collectors, this is a modern rarity with about 100 known examples, as referenced in population reports of coin certification services (ICCS, CCCS, PCGS, NGC).
• 2000P Caribou: two examples are known to exist. They fetch $40,000 or more (ICCS has graded both in MS-64: ICCS 2010 Population report). Both are in private collections.
• 2000P Creativity: two are known to exist. They fetch $15,000 to $20,000 (ICCS has graded one in MS-62 and the other in MS-66: ICCS 2010 Population report).
• 2000P Community: five are known to exist. They fetch $12,000 to $15,000 (ICCS has graded one in MS-60, two in MS-62, and two in MS-63: ICCS 2010 Population report).

Starting in 2011, the mint began selling special sets for newborn babies, birthdays, wedding anniversaries, "Oh Canada" and the Tooth Fairy. The tooth fairy quarters also come packaged separately.^[31]

• The first commemorative coins were planned for 1927 to celebrate Canada's 60th anniversary. A contest was held and the winner for the twenty-five-cent coin was J.A.H. MacDonald; however, the Mint decided to not turn the design into coinage.^[32]
• When coinage was changed in 1937, the caribou (currently on the quarter) was originally planned for the five-cent coin, the beaver (nickel) was planned for the ten-cent coin, and the Bluenose (dime) was planned for the twenty-five-cent coin.^[32]
• The lowest mintage of any circulated quarter post-World War II was in 1991; low mintage was attributed to a work stoppage and using up stock in preparation for the release of the commemorative quarters the following year. The total mintage was a mere 459,000 including collector sets and proofs.^[33]
• Canadian quarters were not issued into circulation in 1997 and 1998. In 1997, only 525,257 quarters were produced. In 1998, only 395,617 quarters were produced; even fewer than in 1991. All of them were issued in collector sets or proofs and none were issued into circulation.
• The caribou on the 25-cent piece dates back to 1936 when a change in the sovereign's image on circulation currency prompted the Canadian government to modify the designs on the reverse side of coins as well. The caribou design was created by Canadian artist Emanuel Hahn, initially used in 1937. It has been temporarily replaced in some years; in 1967 for the Canadian centennial (with a Canada lynx), in 1973 to celebrate the centennial of the North-West Mounted Police, in 1992 for Canada's 125th anniversary, and in 1999 and 2000 by the winning designs of the Millennium coin program.
