Residents on evacuation alert after fire breaks out in Heritage Park in Mission, B.C.

A fire broke out in Fraser River Heritage Park in the Fraser Valley on Tuesday afternoon.

White smoke could be seen above the trees in the largest park in the City of Mission.

Clare Seeley with the City of Mission said the fire broke out just after 10:30 a.m. in a wooded area of the park.

It grew to about 0.8 hectares in size.

The fire forced the evacuation of more than 60 homes on Tooley Place and in Prentis Avenue, above the park.
