Care and Custody
Gap Filler Radar Stations
This HQ is concerned over the risk of injury to unauthorized persons climbing the radar towers at unfenced Gap Filler sites, and the Crown's liability for such injuries.
The following sites previously assigned to ADC for care and custody have radar towers but are unfenced:
| Atikokan | Joint radar and forestry tower is being used by forestry personnel |
| Bridgetown | Site on private land |
| Chapleau | Site on Crown Land |
| Formosa | Site on farm land |
| Lucknow | Site on farm land |
| Sparta | Site on farm land |
| Westport | Site on private land. |
The following additional sites have radar towers, are unfenced, and are herewith assigned to ADC for care and custody:
| Bridgetown | B49-1-1001-1 |
| Lucknow | L37-1-1001-1 |
| Sparta | S111-1-1001-1 |
It is requested that the stairs of the a/n towers (except at Atikokan) be barricaded, and that all sites be well posted with DND No Trespassing signs. The tower at Westport is of particular concern as it is only 5 miles from the summer resort area and has already been climbed by a large number of people, including children.
Costs incurred may be charged to Pri 15 and if any substantial outlay is involved for which funds cannot be made available from the ADC allotment, additional funds will be allotted.
