An ice buildup in Mission Creek has forced the partial closure of the Greenway recreation corridor.
The trails along both sides of the half-kilometre stretch of creek between Gordon Drive and Lakeshore Roads have become unsafe, regional officials say.
The trails will stay closed until further notice.
Apparently, because of the ice buildup, water flows in the creek have been erratic.
The current had been moving at about 10 cubic metres per second on Sunday, but the velocity more than tripled on Monday before dropping back down to five cubic metres on Tuesday.
