A widespread power outage caused by high winds and rain has delayed the funeral for a four-year-old girl who died in a tragic accident at a Santa Claus parade.

A small Nova Scotia town has come together in grief after a little girl was killed during the annual Santa Claus parade in Yarmouth last night.

The girl, who has not been publicly identified, was running along a passing parade float on one of the town's main thoroughfares when she fell underneath it just before 7 p.m. local time, police said.
