Posties out early

Canada Post mail carriers in heat-dome regions were allowed to start their routes in the early-morning hours Thursday, so they're not out during the hottest part of the day.

Spokesman John Caines said Canada Post is also offering mail carriers sunscreen, hats and water.

"They're professionals as well, so they know how to conduct themselves in this kind of weather, but if they can get out early and get the mail before it gets too, too hot and get it all delivered, then it's better for everybody," said Caines.
