Researchers believe that this method causes suffering, as was explained to the mayor.
It appears that most Oak Bay residents are not bothered much, if at all, by the deer - and many enjoy them. All agree that more might be done to reduce the already-small incidence of cars hitting deer, but most of those occur in one area where mitigating factors could be implemented (as was done in Ottawa with significant success). But, no; the mayor's response to such concerns ranged from killing to ... killing.
Other concerns? One was that elderly people were afraid to walk the streets at night for fear of, well, deer attack. (No, they really weren't - and they said so.) Another concern was about deer eating garden plants. Looking at the lush greenery of Oak Bay, boasting the most luxurious gardens in Canada, and thinking of the expanse of snow covering my own garden back home in Ontario, the concern seems laughable. Deer in Victoria, like snow in Toronto, are part of the environment (except that, in Victoria, you can grow so much more, and even year-round). We saw no browse lines and no depleted cedar or other signs of a large population of deer.
