This is the best summary I could come up with:

Anonymized raw survey data shared exclusively with CBC showed that tenants with access to AC reported adverse effects of extreme heat less often than those without.

"The temperature gets upward around 30 C in here as opposed to 33 C just outside on my balcony," said Sandra McCrone, a 64-year-old tenant from South Calgary — even with fans running and blackout curtains blocking out the sunlight during the day.

ACORN's summary report, published Thursday, identified the most common barriers to having air conditioning: high costs, threats of eviction, and lease agreements that prohibit installing AC units.

In half the households where CBC collected data, it showed people spent a majority of time above 26 C — the maximum indoor temperature widely considered safe by experts.

"We've seen people that have had medical prescription notes from their doctor stating, 'This person needs to keep the temperature of the environment cool because they have asthma, or they have a breathing problem, or they have a heart condition,'" she said.

To combat the effects of extreme indoor heat, ACORN is among those calling for provincial or municipal laws that would mandate maximum temperatures in apartments during the summer.
