[1] During World War II, Mould served in the Royal Canadian Air Force and was awarded the Distinguished Flying Cross.
[1] Mould launched a campaign for Chairman of the Municipality of Metropolitan Toronto to succeed William R. Allen, who was retiring.
[5][6] Mould sued Cowan for libel,[7] and while denying any financial stake in Robina, admitted that a company he owned, owed $800 in unpaid taxes to York, a fact that would have disqualified him from running in the 1966 municipal election, had it been known at the time.
[10] The scandal did not abate, with ratepayers associations and members of York Council demanding Mould's resignation as mayor.
[11] After growing pressure,[12] calls on the province to remove him from office, and the announcement by Controller Philip White that he would be running for mayor against Mould in the upcoming election,[13] Mould announced on October 21, 1969, that he would not be standing for re-election in the municipal election in December.
