Toronto’s port authority has announced plans for a C$45 million (£28M) underwater pedestrian tunnel connecting the city’s island airport to the downtown area.
The project will take about two years to complete, it is understood, during which time engineers will bore through 122m of shale underneath Lake Ontario.
Work is scheduled to begin after an environmental impact assessment is completed, most likely in January.
Geoffrey Wilson, the authority’s CEO, said the project would improve access to Billy Bishop Toronto City Airport and meet higher levels of demand.
He added that the job would be financed by a public-private partnership rather than government money, explaining that the move would avoid the levying of a £12.5M improvement fee on users of the airport.
“We know just from the build up for this that there is a very wide group of interest to both finance and build this tunnel from varying parties across Canada and, indeed, North America,” Mr Wilson said.
