Toronto police say people upset about Amber Alert notifications on their cellphones should not call 911.
They say they have received a number of complaints today about being awakened by an alert issued for a three-year-old boy.
Greater Sudbury police issued the alert at about 5 a.m. alleging the boy had been abducted by his mother.
The boy was found safe in Toronto at 8 a.m., and another alert went out to the public.
Toronto police say in a tweet that tying up the 911 lines could mean a slower response to an actual emergency.
Some people posted on Twitter that the Amber Alert system should be changed so it doesn’t wake people living far from where a child goes missing.
