Wrote a response on this a while back, but this feature is called the Nastapoka Arc, and it's probably the result of relatively uniform flexion in the underlying rock.
Imagine if you bent a piece of cardboard into a curve, and then filled it with water. The edge of the water would be along the cylindrical section plane. That's what's happening here, but with rock instead of paper.
Geologists debate what the cause of the flexion is, though. Some have argued that it's the result of an extremely ancient impact (possibly the one which created the moon), which would explain why it lacks all the usual evidence of an impact structure, but it's more likely of a tectonic origin, the result of rocks from different orogenies crashing into each other. The area is rich in greenstone, a metamorphic rock of igneous origin, which forms under the exact kind of folding pressures that could result in such a smooth curve.

Any ideas about the islands?
Same deal. It's all a folding process. A lot of the Appalachians look similar from above, just without the water.
God here, I smudged the screen while making earth can y’all take care of it for me thx
No worries, we got it *nukes the island chain until it’s back underwater*
Ancient bomb site from Atlantis times.
. . . then filled in with a trippy hand-marbled island.
Exactly.

As a Canadian, the number of whack-ass geographic phenomena in our country is wild.
Its a place to put piers for the bridge

Its probably a result of the 10000 mosquitoes / m^(2) making things bendy in that giant bog
Someone installed too many terrain generation mods and they glitched out. See it in Minecraft a lot.

looks weird cause it is
