What do the leading candidates for mayor propose to do about housing affordability? 

If you put together the platforms of the main candidates for mayor, and added an anti-renoviction bylaw, you would start to have a basis for a city housing plan. Here are highlights and links to the full platforms of the main candidates, in alphabetical order: 

Bob Bratina: Include a zone along the LRT corridor where 30 per cent of all new and refurbished housing must be REAL affordable housing. Details at https://votebratina.ca/about/

Andrea Horwath: Leverage land that the City owns or has influence over and establish affordable housing targets for projects built on that land. Details at https://www.andrea4hamilton.ca/actionplan 

Keanin Loomis: Hire staff to speed up approvals of new housing, implementing new housing along major transit lines, and to bring gentle density to established neighbourhoods. Details at https://voteloomis.ca/platform/growing-hamilton-smartly/
