Skyrock was founded in 1986 in Paris, France and plays Rap and R&B music.  Their French Wikipedia entry claims that the Skyrock network is heard on 225 frequencies throughout the country.

Apparently there are some locally operated stations within the Skyrock system with their own separate programming and logo.  I think Radio Peinard is one of them although their website now has Skyrock's logo integrated into it.

CICZ

CICZ "104.1 The Dock" is a Classic Hits station licensed to Midland, Ontario.  From around 1993 until 2008, CICZ carried a Country format branded as "KICX FM".  It's probably obvious to a resident of Midland why the station is known as "The Dock"....all I know is that Wikipedia says that fishing and boating are popular activities in the area and there are a number of marinas and a sailing club based in the town.
