Toronto's mayoral race heads to Scarborough tonight for the second major televised debate in as many nights, with Olivia Chow, Brad Bradford and Chris Alexander all confirmed to attend.

The debate is hosted by the Scarborough Community Renewal Organization at Highland Hall on the University of Toronto Scarborough campus. Doors open at 6:20 p.m. and the event will be broadcast live on CityTV and CityNews, moderated by CityNews anchor Cynthia Mulligan.

It follows last night's United Way, Toronto Star and Toronto Metropolitan University debate, and comes ahead of the CBC Toronto debate at noon on October 8. Advance voting in the municipal election is open October 6 to 11, with election day set for October 26.

With less than three weeks to go before voters head to the polls, the candidates are expected to spar over housing, transit and the cost-of-living pressures dominating the campaign.
