Three emergency organizations in the town of Ste. Anne are holding an open house on Thursday.In previous years, the Fire, Ambulance, Police, and Emergency Measures Organization have seperately held their open houses.  Fire Chief Ken Dayment says it makes sense to combine them and give the public a complete look at all the emergency services available in the community.  The open house takes place at the Fire Hall between 5 and 8 Thursday evening.  Police Chief Marc Saindon says this is a great opportunity for the public to meet with emergency personnel and ask questions.
