low income with a house? I don't think so.
Property & Sales Tax Credits, yes
However:
Property tax does not include:
* 'user charges' billed by a municipality (e.g. water)
* 'common expenses' incurred by condominium owners
* mortgage principal and interest
* property tax interest and/or penalty charges
* the portion of local improvement payments financed by government agencies (you may claim your actual payment for the local improvement)
* property tax for the portion of a residence used for a business. http://www.rev.gov.on.ca/en/bulletins/itrp/6303.html
