In your article you mention keeping receipts for the ecoEnergy Retrofit grants.  This grant is given only if the homeowner gets an energy evaluation before they do their renovations.  Receipts won’t help if they do the work without getting this evaluation done first.  There’s a good explanation of these grants and the Home Renovation Tax Credit in the fact sheet at http://oee.nrcan.gc.ca/residential/personal/grants.cfm?attr=4  One important point too is that the grants increased by 25% on March 30th!
