PUBLIC SERVICE ANNOUNCEMENT - Monthly Test of CFB Esquimalt's Mass Notification System



Public Service Announcement

Bentinck Island Range

February 13, 2018 – Esquimalt, B.C. – Department of National Defence/ Royal Canadian Navy

The land-based demolition range at Bentinck Island will be in use 8:00 a.m. to 4:30 p.m. daily from Monday February 19, 2018 to Friday February 23, 2018.

Bentinck Island is located near Race Rocks in the Strait of Juan de Fuca.  Used as a terrestrial demolition range by the Canadian Armed Forces, local residents will likely be unaware of the activities except on days when environmental conditions such as temperature, humidity and wind direction affect how far the sound will travel.

Numerous studies have been conducted on the potential environmental effects of Bentinck Island demolitions.  Specifically, blast noise in the marine environment during land-based demolitions is almost undetectable by acoustic equipment above that of other underwater background sounds such as waves and marine life.

The public is reminded that no unauthorized person may enter this area and trespassing is prohibited. 


Controlled Blasting at CFB Esquimalt – Colwood


February 9, 2018 – Colwood, B.C. – Department of National Defence / Royal Canadian Navy


Residents in the vicinity of CFB Esquimalt – Colwood may hear noise as a result of controlled blasting and excavation activities beginning February 14th, 2018. Blasting will occur up to three times per day Monday to Friday, 9 a.m. – 4:30 p.m. and is expected to continue until approximately February 23rd, 2018.


It will be limited to a controlled site and poses no danger to neighbouring residents. Pre-blast signals (12 short whistles) followed by the All-Clear (5 second whistle) will likely be the only audible noise for residents as blasting activities are small in scale, very limited in scope, and conducted by experts with extensive experience.


This work supports the environmental remediation of CFB Esquimalt – Colwood.
