Watch Item
Dry, cool weather continues under high pressure from Quebec through the weekend. Two frosty nights in a row in the Greater Toronto Area means the growing season is ending for tender plants. Disconnect garden hoses and shut off outdoor taps from inside before the first hard freeze.
Living Ready
Electricity prices fall November 1, and the rebate shrinks
Starting November 1, prices fall on all three regulated plans. Time-of-use runs 9.1 cents off-peak, 14.6 mid-peak, and 18.9 on-peak per kilowatt hour, the ultra-low overnight rate is 3.7 cents, and tiered pricing is 11.2 cents for the first 1,000 kilowatt hours and 13.2 after that. The Ontario Electricity Rebate drops to 15.7 percent, which the province estimates is about $23 a month for a home using 700 kilowatt hours, down from about $36. Look at your last bill to see which plan you are on, and keep laundry and the dishwasher in off-peak hours.

Insulation and air sealing rebates before the heating season
Save on Energy's Home Renovation Savings Program pays up to $1,250 for attic insulation and up to $7,500 for a cold-climate air source heat pump, with no home energy assessment needed for those single upgrades. With an assessment and two or more upgrades, it pays up to $7,700 for insulation, up to $250 for air sealing, and $100 per window or door opening. A well-insulated, sealed house holds its heat longer during a winter outage, and costs less to heat every other day.
