If that means "radio" waves, then this goes a long way to explaining why 
there's already limited capacity even near the US-Canada border.

Waves in this case generally refers to 10G/100G leased optical circuit capacity. 

Thanks for clearing this up, that makes sense now!

Now I note that a single Starlink ground station is generally within sight of and set up to handle multiple satellite links (all known images show 6 or more radomes). As each bird has ~20 Gb/s capacity, I guess we'll probably be talking 100G circuits here (where they can get them). And the move to dark fibre is a logical step then.
