The Progressive Conservative Party of Ontario has issued an apology after coming under fire for sending out campaign donation requests to residents designed to look like invoices. In a statement, the PC party said it “regrets” that the correspondence was sent out. “At no time was it our intention to mislead our valued supporters. We regret that this correspondence was sent to a limited group of supporters by one of our vendors and will not happen again,” the party said Thursday. “We apologize for any confusion or frustration this may have caused.” The vendor mentioned by the PCs is a Toronto-based marketing company called The Responsive Marketing Group (TRMG), which shares the same address listed on the fake invoices. CTV News Toronto has reached out to TRMG for comment but has yet to receive a response. Political analyst Jim Warren told CTV News Toronto Thursday that political fundraising efforts are often contracted out to third parties. “A lot of their operations is either outsourced to volunteers or, in the case of fundraising, often to outside parties so this is completely normal,” Warren said.
