On September 19, 2017, Ritz caused controversy when he tweeted a link to a news story stating no industrialized nations were on pace to meet Paris Agreement carbon emission targets with the comment "Has anyone told our climate Barbie! " (referring to Environment Minister Catherine McKenna). Ritz deleted the original post within 20 minutes, afterward posted another message stating: "I apologize for the use of Barbie, it is not reflective of the role the Minister plays". Conservative leader Andrew Scheer condemned Ritz's comment later in the day and stated he would reach out to McKenna personally to "assure the minister that this type of behavior has no place in the Conservative caucus". The next day Ritz's office issued a statement confirming his resignation from the House of Commons effective October 2, 2017.
