. Four operational variations of CADPAT have been used by the Canadian Armed Forces: a temperate woodland pattern, an arid regions pattern, a winter operations pattern, and a multi-terrain pattern.
CADPAT was the first digital camouflage pattern to be used operationally, having been issued in 1997 with the Canadian Armed Forces. The pattern became fully standardized within the Canadian Armed Forces by 2002, having completely replaced the olive-drab operational uniforms formerly used by
Regular Force units. Development of the multi-terrain CADPAT variant began in 2019 and is being issued to replace temperate woodland and arid CADPAT variants.
History

countries. The first research effort, called Integrated Protective Clothing and Equipment (IPCE) Technology Demonstration, was initiated in 1995 but then was cancelled, due to high systems cost and failure to meet the majority of the requirements. Ongoing operations in the mid-1990s led to the creation of the Clothe the Soldier (CTS) Project, which directly addressed the NATO soldier system capability areas of survivability and sustainability. The Canadian Disruptive Pattern was a part of ongoing research and implemented during the CTS Project.
Once CADPAT temperate woodland was finalized, field tests began in 1995. After satisfactory results, CADPAT was adopted by the Canadian Army in 1997; however, testing was not concluded until 2001 once the pattern was trademarked.

The first operational use of the temperate woodland pattern was reported in September 2001 with Canadian soldiers serving in

, when Taliban prisoners of war were seen escorted by armed Canadian commandos in the camo. This nearly made things complicated for the
Department of National Defence (DND), since it had said that no Canadian commandos were officially in Afghanistan.
In 2019, tests were conducted for plans to eventually replace the temperate and arid regions patterns.
The 3rd Battalion of the
Royal Canadian Regiment (3RCR) in
Garrison Petawawa were issued the pattern for field tests.
Under the Soldier Operational Clothing and Equipment Modernization (SOCEM) project, DND sought feedback and advice from users for the trial camouflage known as Prototype J before it made its decision.
In 2021, the new multi-terrain CADPAT was selected as the replacement.
In 2021, the first orders for the MT pattern were made, with 390,000 metres of cloth, followed by 560,000 metres of cloth. The new camouflage pattern is expected to be fully adopted by 2027.

Pattern variations
The Canadian Armed Forces has developed four operational variations of CADPAT: temperate woodland (TW), arid regions (AR), winter operations (WO), and multi-terrain (MT).[
The temperate woodland pattern became the standard issue for Land Force Command in 2002, with the Air Command following suit in 2004. In 2021, the Canadian Armed Forces selected a new CADPAT variant, multi-terrain pattern, to replace the TW and AR patterns, with both being phased out over the coming years, and the MT-patterned uniform becoming the "daily wear" uniform.]
Temperate woodland
The temperate woodland pattern (TW) is designed for use in forest and grassland environments, with its mix of light green, dark green, brown, and black.[
The pattern was first introduced in 1996 on the helmet cover for the new CG634 helmet then coming into service. At the same time, the pattern was also introduced on a new soldier's individual camouflage net. The TW pattern provides protection from observation by the naked eye and night vision devices, with the pattern incorporating ]near-infrared

technology at the ink level to help conceal the wearer against near-infrared optical devices.
The pattern is optimized for a gate rate of 30 to 350 metres against a 3-power optical sight.
Arid regions
The arid regions pattern (AR) is designed for use in desert, near desert, and savannah

conditions, incorporating three shades of brown.[ The AR pattern also features two additional arm pockets and Velcro on the arms compared to the older TW uniform.] The AR pattern was developed concurrently with the trials of TW pattern.
After Canadian Forces were deployed to Afghanistan, the AR pattern was expedited with the intent that it would be issued to soldiers in summer 2002. The AR pattern also incorporates infrared technology for night operation.[
]
Winter operations
The winter operations (WO) pattern was created for snow-covered or mixed woodland and snowy terrain.[ The snow camouflage pattern was introduced as an upgrade to the monochrome winter whites to further enhance the Canadian soldier's camouflage capability by day and night. It also includes near-infrared technology.][

Multi-terrain
Beginning in 2019, as part of the Soldier Operational Clothing and Equipment Modernization (SOCEM) programme, a 'transitional' pattern began to be tested by the Canadian Armed Forces. The pattern was accepted after some mild alterations to its coloration. The pattern is medium-brown dominant, accented by black, dark green, and light tan; overall it is less vibrant than the TW pattern, but darker than the AR pattern.
In 2021, the new CADPAT pattern, called "multi-terrain pattern" or simply “MT,” was announced as the replacement the TW and AR patterns.
The MT pattern is designed to blend into the wide range of environments, and is planned to serve as the day-to-day working uniform of the Canadian Armed Forces. In 2024, the Canadian Forces announced that issuance of MT-patterned uniforms would begin in February 2024 for high-readiness units first; They also claimed that the transition to the new pattern would be complete by 2026.
Proposed variations
In 2011, Defence Research and Development Canada, based at CFB Suffield, set forth a requirement to develop a new urban pattern for the Canadian Forces based on the three major metropolitan areas of Canada: Toronto
Toronto ( , locally pronounced or ) is the List of the largest municipalities in Canada by population, most populous city in Canada. It is the capital city of the Provinces and territories of Canada, Canadian province of Ontario. With a p ...

. The prototype pattern is known as the Canadian urban environment pattern (CUEPAT). While at least one company HyperStealth Biotechnology Corporation responded to the requirement, there have been no further announcements regarding CUEPAT.
During the trials that eventually led to the Multi-Terrain pattern, a number of patterns emerged as contenders, most prominent of which was known as the 'Prototype J' pattern. It underwent testing in 2019 and the pattern was slightly more green-dominant than the ultimately adopted MT pattern.
