Spark are attempting to shift many previously copper-based broadband connections to a cellular provisioned service, in order to ostensibly improve service, but no doubt increase their margins given Spark own the cell towers (medium).
Spark have connection agreements with all the major LFC's, so the answer to your question is yes, you can use Spark to provide you with broadband across fibre
Disc: To keep things simple, I am omitting any reference to fibre owned and laid outside of the UFB agreement, and omitting any discussion about RSP's who don't have interconnection agreements with some LFC's.
