Dufferin—Caledon is a federal electoral district in Ontario, Canada, that has been represented in the House of Commons of Canada since 2004. It was created in 2003 from parts of Dufferin—Peel—Wellington—Grey riding. This riding gained a fraction of territory from Vaughan during the 2012 electoral redistribution. After David Tilson's resignation, in March 2019 the Dufferin—Caledon nomination for the Conservative Party in the 2019 election was won by Harzadan Singh Khattra, amid accusations within the party of vote tampering, membership reimbursement, and payments to foreign students to attend, despite their ineligibility within party rules.
