Neighbours checking on neighbours
A group of tenants in Vancouver's Downtown Eastside is proving that community, not just air conditioning, can be a lifeline during extreme heat events. According to a report from CBC's What On Earth, residents in the neighbourhood have been organizing to make their buildings safer when temperatures climb to dangerous levels.
The Downtown Eastside is home to many low-income residents, including seniors and people with health conditions that make them especially vulnerable to heat. Older buildings in the area often lack air conditioning, and units can turn into ovens during a heat dome. Rather than waiting for a top-down fix, tenants have taken it upon themselves to build informal safety networks: checking in on elderly or isolated neighbours, sharing information about cooling centres, and coordinating access to fans or cool spaces within their buildings.
Why this matters beyond Vancouver
Extreme heat has become one of the deadliest weather threats in Canada. The 2021 heat dome that hit British Columbia was linked to hundreds of deaths, many of them in older apartment buildings without cooling, and many among people who lived alone. That tragedy pushed municipalities and housing advocates across the country to rethink how prepared communities actually are when a heat warning is issued.
What's happening in the Downtown Eastside offers a grassroots blueprint that other cities, including Ottawa, could learn from. Ottawa summers have brought their own share of heat warnings and humidex readings well into the 40s in recent years, and the city, like most Canadian municipalities, relies heavily on residents knowing where cooling centres are and checking on vulnerable neighbours themselves. A tenant-led buddy system, like the one described in Vancouver, doesn't require new infrastructure or funding, just organization and a bit of coordination among people who already live in the same building.
The bigger picture
Housing advocates have long argued that heat safety shouldn't fall entirely on individual tenants, especially in aging rental stock where landlords are slow to install air conditioning or improve insulation. But as climate change drives more frequent and intense heat waves across Canada, community-led efforts like this one are filling gaps that policy hasn't caught up to yet.
For renters anywhere in the country, the takeaway is simple: knowing your neighbours and having a plan before a heat warning hits can make a real difference. Whether it's a phone tree, a shared cooling space, or just knocking on a door to check in, these small acts of organization are proving to be some of the most effective heat safety tools available right now.
