The two electronics distribution companies from Montreal – Cpunto Inc and Electronic Network Inc – were listed for “acting contrary to the national security or foreign policy interests of the US” and are subject to US export restrictions, according to the US Commerce Department.

The US government on Thursday called on companies to ensure they comply with Russia-related sanctions imposed after Moscow’s invasion of Ukraine, warning that a failure to do so could lead to potential prosecution or enforcement actions.

The Commerce Department recently imposed export curbs on nearly 90 Russian and third-country companies and prohibited them from buying items such as semiconductors.

The Canada Border Services Agency told CBC News on Monday that the two sanctioned companies were identified as part of a “global effort” to support Russia. The agency did not immediately respond to a request for comment.

The Commerce Department list did not mention what the two companies shipped or attempted to ship that triggered US action.

Alexander Yermukov, a director at Cpunto, told CBC News his firm took this matter “very seriously, as we have always been acting in good faith without intention to defraud, deceive or in any way act maliciously.” He added the company intended to engage further to address the concerns but could not comment on any specifics at this point.

The two companies did not immediately respond to Reuters requests for comment.
