The RCMP said Wednesday that Sami Abdellah Bebawi has been charged in a separate case with obstructing justice.
Bebawi was charged with Constantine Andreas Kyres, who also faces extortion and obstructing justice, stemming from the alleged corruption of foreign public officials.
The acts allegedly occurred between 2012 and 2014.
In February, Bebawi was charged with fraud over $5,000; two counts of laundering proceeds of crime; four counts of possession of property obtained by crime; and bribing a foreign public official.
Bebawi is already wanted on a Canada-wide arrest warrant on those earlier charges, which stem from crimes that allegedly took place between 2001 and 2013.
A new warrant was issued for his arrest Wednesday, while Kyres is to appear in court on Sept. 18.
Several former SNC-Lavalin executives have been charged criminally after corruption investigations.
