No. In the in-movie fiction both the tunnel and the entrance was in Greenland.
But in reality they were shooting the entrance scenes somewhere else. In Iceland in this case.
This happens quite frequently in movies. Toronto or Budapest frequently stands in to all kind of other cities for production reasons. (A subway escalator from Budapest even shows up on the space station of Alien: Romulus)
Toronto skyline is often apparent in 'New York' scenes, in many productions, Suits for example. It's like they think only NYC will be recognisable (formerly the twin towers, ESB, statue of liberty, etc.) so any view of Toronto can just sub in for an anonymous bit of NYC. (Except perhaps the CN tower, haven't seen anything that stupid!)
This was the source of humour in "Star Trek: Strange New Worlds" S2E3 where Kirk stands in Sankofa Square in front of a large sign emblazoned "Toronto Eaton Centre" and asks "Are we in New York City?"
Lots of film production goes on in Toronto, I especially love how Roy Thompson Hall always shows up in anything vaguely sci-fi. Vaught headquarters in The Boys, U.N. headquarters in The Expanse, it was even in the background of a few scenes of The Handmaid's Tale.
"The Ontario Film & Television Tax Credit is a 35% refundable tax credit on Ontario labour for film and television productions by Ontario-based Canadian controlled companies for productions shot in Toronto, Ontario."
Same general reason why a lot of film/tv production is done in the state of GA now, which decided to compete with California, Vancouver and Toronto to attract productions.
I'm not saying they should film in NY, I meant the lack of care to use less recognisable bits or remove them digitally etc. - that they think 'we can't film in NYC, people will recognise it, and this isn't set in NYC' - not that they were trying to film NYC and should do it in NYC. (But I realise now I made that confusing with the Suits example.)
Vancouver filming in the 1990s was worse, there's a Jackie Chan movie supposedly set in NYC where you can see a clear view of the snow capped north shore mountains across the water.
The 'new' Vancouver Public Library also serves as the headquarters of an evil human cloning corporation in "The 6th Day", and is seen in Battlestar Galactica.
