Elections Canada delivered special ballots via helicopter to lighthouse keepers living on remote islands along B.C.鈥檚 coast in the lead-up to last month鈥檚 federal election.

The government agency -- which has delivered ballots by boat, snowmobile and plane in the past -- used a chopper owned by the Canadian Coast Guard for three days in October to shuttle two Elections Canada service agents to 27 lighthouses.

In total, 58 people living on the islands voted ahead of the Oct. 21 election day.

It鈥檚 not the first time Elections Canada has provided the service, according to Elections Canada media relations鈥 senior adviser Natasha Gauthier.

鈥淚t is Elections Canada鈥檚 mandate to make sure every eligible elector is able to cast their ballot, and we will make every possible effort to allow them to do that,鈥 Gauthier told CTVNews.ca in a phone interview.

Elections Canada could not provide a price tag for the trip but said they were 鈥減iggybacking鈥 on an existing Coast Guard cargo trip 鈥 a standard practice to save on costs.

鈥淚t鈥檚 not like Elections Canada is incurring a huge cost to take those ballots out. It鈥檚 the staff, their time, and they鈥檙e hired to work the election anyway,鈥 Gauthier said.

Mail-in ballots weren鈥檛 an option, Gauthier said, because the lighthouses 鈥 which are all operated by the government -- don鈥檛 have regular mail access.

Canada鈥檚 population is highly concentrated along the southern border. According to a 2016 Statistics Canada report, 66 per cent of the population lives within 100 kilometres of the U.S.-Canada border.

For those living in the hardest to reach areas, Elections Canada is sometimes forced to get creative. Every election, the Voisey鈥檚 Bay Mine in Labrador pays for a plane and pilot to transport Elections Canada agents to the mine to allow the 700 or so workers to vote.

When a sudden October snowstorm wiped out power and forced the evacuations of 13 First Nations communities in Manitoba, Elections Canada set up what鈥檚 called a 鈥渟uper poll鈥 in Winnipeg to help displaced people vote in their ridings back home. Similar efforts were made for hydro workers working to restore power.

Around the Elections Canada offices, there are rumours that a dog sled was once used to ferry ballots from an isolated northern community.

鈥淭hat remains an urban legend around here,鈥 Gauthier said.
