Anyone living near CFB Esquimalt may hear whistles and blastings starting tonight and running weekly until Oct. 1.
The controlled blastings are scheduled to run between 7 p.m. and 10 p.m., and will happen during high tides to mitigate environmental efforts.
Before the blasts there will be 12 pre-blast whistles, and afterwards there will be five more whistles.
Base officials stress that all blasting will be in a controlled site and pose no danger to neighbours. They say explosions are small in scale, and residents are much more likely to hear the whistles than anything else.
