Elizabeth May spent more than any other federal party leader to secure her seat in last October's election.
Financial reports filed with Elections Canada show the Green Party leader spent almost $230,000 to win her Saanich-Gulf Islands riding. She was the only Green candidate to win a seat in the Oct. 19 vote.
Justin Trudeau, who led his Liberals to victory, spent just over $183,000 to hang onto his Montreal riding of Papineau.
Stephen Harper, whose Conservative government was defeated, spent just over $117,000 to easily win his Calgary Heritage riding.
NDP Leader Tom Mulcair spent the least: less than $105,000 to hold his Montreal riding of Outremont.
The totals for each leader include expenses that were subject to campaign spending limits plus other reportable expenses which fell outside the cap.
