Toronto's mayoral race sharpened on Monday as Olivia Chow used a campaign stop to accuse her main rival, Brad Bradford, of "giving away control" of Toronto's water supply to the Ford government at Queen's Park. Chow listed what she described as her record in office while taking aim at Bradford's platform, CP24 reported.

Bradford spent the same stretch of the campaign renewing a different pledge: a line-by-line review of Toronto's spending, which he said would be the first since 2011. He argued Chow has "made her peace with less" while the city is, in his words, not close to reaching its full potential.

The exchanges come with one week left before election day in a race CP24 describes as neck-and-neck. Reporters talking to voters across the city this week found affordability and transit at the top of the priority list, the two issues both campaigns have been circling since the fall.

Neither campaign released new polling on Monday. Voters choose Toronto's next mayor next week, and both camps are expected to spend the final days on transit, housing costs and the city's relationship with the province.
