Peel Regional Council has passed a motion that aims to reduce the role of police in mental health calls in some situations.
But the motion, which also asks for a plan to increase the number of the region's Mobile Crisis Rapid Response Teams (MCRRT), would need provincial cooperation to see widespread implementation.
Coun. Dipika Damerla, who moved the motion, called it a "fundamental shift" in the way officials would respond to mental health calls.
"It's something I've been very interested in for some time," she told CBC News, adding that the fatal shooting of Ejaz Choudhry by Peel police just brought the issue back to the forefront. Choudhry's family called a non-emergency line last month when the 62-year-old was in a mental health crisis, but in the end, he was killed.
The province's police watchdog, the Special Investigations Unit, is examining the circumstances of his death.
