The Health Department in Hamilton has quietly scrapped its policy of issuing heat alerts.
They don't believe they work and don't believe the city's weather is extreme enough to justify issuing them.
Hamilton is now the only lakeside city between Toronto and the U.S. border to stop warning people about the health risks during a heat wave.
The alerts became widespread following a 1995 heat wave, in Chicago, that killed more than 500 people.
The news comes as an extreme heat alert was issued by Toronto Public Health at the start of what is expected to be a sweltering week for the city and much of Ontario.
An extreme heat alert is issued when the high temperatures are such that the chance of additional deaths - above those that are typically experienced during the same time of year - is more than 90 per cent.
Temperatures in Toronto peaked at 34 C but felt more like 42 C with the humidity factored in. The high temperatures are expected to continue through Wednesday. source.
