A country that assumed it did not need to worry about this
Canadian long-term care homes were designed around winter. Heating systems, insulation, windows built to keep warmth in — and, in a great many buildings, no cooling at all beyond a few fans and a shaded lounge. That assumption held for decades and then stopped holding.
The two events that changed the conversation are worth naming, because they explain why the rules differ so sharply from one province to the next: the deaths during the 2018 heat wave in central Canada, and the 2021 heat dome in British Columbia, which killed hundreds of people, most of them older and most of them indoors.
The single most useful thing to know
There is no national standard. Long-term care is regulated provincially, and on heat the provinces have diverged more than on almost any other issue.
Ontario went furthest: homes are required to provide air conditioning in resident bedrooms, on top of the long-standing requirement for designated cooling areas and temperature monitoring in resident areas. British Columbia, after the heat dome, built out a formal alert framework with two escalating levels — a heat warning and an extreme heat emergency — and pushed cooling into care settings. Most other provinces have guidance, expectations and inspection standards, but nothing that guarantees your mother a cooled bedroom.
So the first question is not about the home. It is about the province: what is actually required here — a cooled bedroom, a cooled common area, or nothing in particular? Once you know that, you know whether you are asking the home to comply or asking it to do better than the law requires. Those are different conversations and they get different results.
The warnings are public
Environment and Climate Change Canada issues heat warnings using criteria set with each province, so the trigger temperatures in Manitoba are not those in Nova Scotia. In British Columbia the second tier, the extreme heat emergency, exists precisely because 2021 showed that an ordinary warning did not convey what was coming.
These are public and they are for the area where the home is, not where you are. Ask the home who checks them each morning in summer. Where nobody can name that person, there is no system — there is luck.
Her room, not the lobby
The lobby is always comfortable. Ask about her room: which way does it face, does it get afternoon sun, what does the thermometer read at four in the afternoon and what does it read at eleven at night? Nights matter more than afternoons for older people, and a room that never drops below 28°C is where the damage accumulates.
If the bedroom is not cooled, ask the follow-up in its concrete form: which room is the cooling area, how many residents fit, how many hours a day is she actually in it, and what happens overnight? A lounge that seats twenty in a home of a hundred and sixty is not an answer — it is a rotation problem somebody needs to have solved in writing.
Ask about backup power too. A heat event and a grid failure arrive together more often than anyone plans for, and a generator that runs the lights, the lifts and the call bells is not the same as one that runs the cooling.
The medications nobody reviews
The most neglected part and the easiest to fix. Several drug classes very common in long-term care raise heat risk: diuretics, which worsen dehydration; antipsychotics and other psychotropics, which impair temperature regulation; anticholinergics, which reduce sweating; and some antihypertensives, which with heat-driven vasodilation drop blood pressure and cause falls.
This is not an argument for stopping anything — stopping medication is dangerous and is not a family decision. It means the attending physician or nurse practitioner should review the regimen when a warning is issued, adjusting doses and timing. Ask directly: has her medication been reviewed for the heat, and by whom? In most cases the honest answer is no, and asking is usually enough. Put it on the agenda of the next care conference so it lands in the record.
What should change on a warning day
- Supervised hydration — not a jug left with someone who cannot lift it, but rounds with a record of what was actually drunk. Thickened fluids in quantity for residents with swallowing problems.
- Temperature checks more often for at-risk residents, not only on request.
- Weight monitored — rapid loss over a few hot days is dehydration until proven otherwise.
- Activities moved to mornings and evenings rather than cancelled; immobility has its own cost.
- Bedding and clothing changed — it happens that the winter duvet stays on because it is the one in the closet.
- A lower threshold for calling the physician, with written criteria: new confusion, unusual drowsiness, passing little urine, dry skin.
Heatstroke does not look like "feeling hot"
In an older person it looks like sudden confusion, drowsiness, weakness, sometimes hot dry skin with no sweating. That is not "a bit wilted by the weather". It is an emergency, and it is 911.
Six questions to ask
- What does this province require — cooled bedrooms, cooled common areas, or neither?
- What does her room read at four in the afternoon and at eleven at night?
- If the bedroom is not cooled: which room, how many spaces, how many hours, and what about overnight?
- Does backup power run the cooling, and when was it last tested?
- Has her medication been reviewed for the heat, and by whom?
- What are staffing levels in July and August compared with March?
If you get nowhere
Put it in writing to the director of care: one question, one date. The home's family council is a real lever and an underused one — a question raised there goes on a record the home must respond to. Beyond that, every province runs a complaints and inspection line for long-term care, and your local public health unit is the right destination for anything about heat response.
Keep copies, and photograph the room thermometer with the date visible. In a home where the director of care changes every couple of years, the family with the file is the only one with a memory.
Where to start
If your mother is already in a home, send those six questions in writing today rather than at the end of August. A written request in July gets answers; the same request after an incident gets explanations.
If you are still choosing, you are touring in the month when a building's limits are visible. Walk into the resident lounge at four in the afternoon and stand there for five minutes.
If you would rather not run it alone, we can. For CA$99 we take down your mother's situation, look for the homes in your area that answer these questions properly, and report back what they told us, with names and dates. Start here
