A statement from his spokesperson indicates that Ford is attending a meeting with the board of directors of Build Toronto on Thursday morning.
Ford wants to use revenue generated by Build Toronto, the city's real-estate and development corporation, to help fund subway expansion, according to the statement.
Ford is due to speak to the media at 12:15 p.m.
On Wednesday afternoon, Ford came out swinging against John Tory, slamming his mayoral rival's work and political experience. He suggested that Tory is "not prepared" to be the city's next mayor.
Ford was a last-minute entry to the mayoral race, registering to run in Mayor Rob Ford's place.
The mayor withdrew from the race after doctors discovered a tumour in his abdomen. He has since been diagnosed with liposarcoma, a rare type of cancer.
For the past four years, Doug Ford has been a member of city council, as his brother served as mayor.
He came to politics from Deco Labels & Tags, a company founded by his late father.
