Canada's Airbus affair, in which he was alleged to have arranged secret commissions to be paid to Brian Mulroney and lobbyist Frank Moores in exchange for then Crown corporation Air Canada's purchase of Airbus jets. There has never been any evidence produced to substantiate this allegation. Both Schreiber and Mulroney deny such is the case. Mulroney sued the government of Canada for libel, and in early 1997 received a $2.1 million (CDN) settlement and an apology. During an examination under oath, Mulroney claimed that he hardly knew Schreiber, and had had no business dealings with him. Schreiber allegedly made payments of $300,000 in cash, in three instalments, to Brian Mulroney beginning one month after Mulroney had stepped down as Prime Minister but while Mulroney was still a sitting member of Parliament. Schreiber had previously been a fund raiser in Mulroney's successful campaign to win the 1983 Progressive Conservative leadership convention. Mulroney has since admitted to receiving $225,000 from Schreiber, in cash, and not reporting this in his income tax returns until eight years later, subsequent to Schreiber's indictment in Germany for bribery, tax evasion and fraud and extradition order from Canada.

On 24 March 2007, he filed suit in the Ontario Superior Court against Brian Mulroney for services not rendered. He alleged that he had made payments to Mulroney in 1993 and 1994 totalling $300,000 in cash in equal instalments of $100,000; that Mulroney had agreed to aid in the building of a factory to make light armoured vehicles in Quebec; and that Mulroney never held up his end of the bargain. In October 2007, Schreiber had apparently exhausted all avenues of legal appeal regarding his extradition to Germany and was set to be extradited to face charges. However, his lawyers, Edward Greenspan and Gary Botting, made a last-ditch motion using a rarely used provision,
