Environment and Climate Change Canada listed 54 active alerts across the country when its alert map was read at about 1:10 a.m. Eastern this morning. The map names which provinces carry alerts but does not expose what kind they are, so this brief does not name an alert type. For the specific alert on your community, weather.gc.ca is the authoritative source and it takes about a minute to check.

Ontario is not among the provinces named in that list this morning, which means there is nothing active in the province to respond to today.

A quiet day is a good day. It is also most of them, and treating it as normal rather than as the absence of something is the right way to read it.

National Canadian wildfire statistics could not be refreshed this run. The Canadian Interagency Forest Fire Centre situation report and the Canadian Wildland Fire Information System both refused to return readable data, so this brief gives no national fire count rather than repeating an older one as though it were current.

No grid emergencies, water system disruptions, or major transportation closures are reported across Ontario this morning.

No public health advisories specific to Ontario were confirmed this run.

Ontario's defining hazard is not summer weather. It is the ice storm, and the reason it deserves attention in September rather than January is that the preparation it rewards takes weeks to arrange and minutes to use.

An ice storm's damage is almost entirely to the electrical distribution system, and the outages it causes are measured in days rather than hours because crews have to work through blocked roads to reach lines that are still coming down. That is a different problem from a summer thunderstorm outage, and it asks different things of a household: heat that does not depend on the grid, water that does not depend on a pump, and a plan for several days rather than one evening.

The September version of that work is unglamorous. Have whatever heats your home serviced now rather than in November, when the wait is weeks. Test the carbon monoxide alarms on every level of the house and outside sleeping areas, and replace any that are past their manufacturer's replacement date. If you own a generator, start it and run it under load before the season rather than during it, and be clear in advance about where it will sit, because the answer is always outdoors and well away from the house.

The other half is water. Households on a well lose water the moment the power goes, and that surprises people every winter. Several days of stored drinking water is the single cheapest thing on this list.

For alerts specific to your community, weather.gc.ca is the authoritative source, and Ontario also runs provincial emergency alerting through Alert Ready on mobile phones.
