This confirms the finding in Levy's A sample by the World Anti-Doping Agency (WADA) from an out of competition test last month, in Canada.
It is understood that GW501516-Sulfoxide and GW501516-Sulfone, are the substances found in Levy's sample.
A four-year ban would rule the 31-year-old Westmoreland native out of next year's Paris Olympics, as well as the next two World Athletics Championships editions in 2025 and 2027.
Levy, who also has a 2018 Commonwealth Gold medal in his accolade, had earlier this month confirmed being notified of the adverse analytical finding on November 3, and vowed to defend his integrity, as he "is certain he did not knowingly breach the rules."
In 2019, Russia was handed a four-year ban from major international sporting events by the World Anti-Doping Agency (WADA).
WADA declared the Russian Anti-Doping Agency (RUSADA) non-compliant over inconsistencies in anti-doping data discovered during an investigation.
At the time, the International Olympic Committee (IOC) reiterated its support for Russia's ban, which meant athletes would be unable to compete under the Russian flag at the 2020 Olympics or the 2022 Winter Games.
In a landmark move on Thursday, the Court of Arbitration for Sport (CAS) confirmed Russia would be banned, albeit with the time frame cut from four years to two.
That will still discount Russia from participating in the Tokyo Olympics – pushed back to 2021 due to the coronavirus pandemic – plus the Winter Games in Beijing in 2022, and the next World Cup.
Russia will, however, be able to compete at the Euro 2020 football finals, which is also scheduled to take place next year, having been another event impacted by COVID-19.
This is because WADA's international standard for code compliance by signatories does not list UEFA as a "major event organisation".
Russian athletes wishing to compete at the Tokyo and Beijing Games will be able to do so, but only under a neutral banner.
CAS stated in its announcement: "This panel has imposed consequences to reflect the nature and seriousness of the non-compliance [to the WADC] and to ensure that the integrity of sport against the scourge of doping is maintained.
"The consequences which the panel has decided to impose are not as extensive as those sought by WADA. This should not, however, be read as any validation of the conduct of RUSADA or the Russian authorities."
CAS also said that its ruling aims to "effect cultural change and encourage the next generation of Russian athletes to participate in clean international sport".
In order to be reinstated at the end of the two-year ban, it was also ruled that RUSADA must pay a contribution of $1.27million to WADA, in respect of the costs incurred in investigating the authenticity of the data retrieved from the Moscow laboratory in January 2019.
RUSADA, under supervision from WADA or the Athletics Integrity Unit (AIU), was told it must conduct investigations into any cases impacted by the deletions or alterations of the Moscow laboratory data.
The Russian organisation must also provide any other support requested by WADA to assist in determining whether athletes whose samples are listed in the Moscow laboratory database have a case to answer.
