I apologize to everyone.
In this map of the state of Tocantins you can see the size of the absurd that did.
The island in question is in the lower left corner.

Very interesting thread! Given that I'm Minnesotan I well acquainted with lakes, we have thousands of them gouged out by ice sheets during the last ice age. An observation I've made is that besides lots of lakes the glaciers left the local-scale drainage patterns a bit messed up and erratic in places with stream-water going short distances zig-zagging from lake to lake until a substantial river with a flood-plain is reached.
I guess the more modern the geology the more weird its going to look. Even with extremely recent geology the water should still adhere to these general principles because water moves so fast in comparison to changes in rock. Your area showing the zigzags of streams all finding a new and comparatively fresh path to the sea should convince us all that it has to be this way.
yeah, canada has a crapload of lakes, mostly in the norther regions.
These lakes (in the band you mention above) are generally caused by glacial advance and retreat... the glaciers essentially scrape off the land as they advance, and as they retreat, they dump everything they scraped up and move backwards... this creates large holes where the softer rocks wear away faster... but also the deposits the glacier makes can create lakes as well. heres an example of what we mean by a lot of lakes, this is near winnipeg, but areas all along canada have similar lakes.

That looks like a lot of fun, fishing, kayaking, etc.

I'd like to make notice of the fact that the lakes from the ice age glacier retreat can be temporary if shallow enough. Here in Finland I have seen a few examples of shallow lakes that slowly die because they turn to swamps.
