Fixed RNAV Routes

Does anyone know what a fixed RNAV route is? There are only three defined in Canada:

T101: Firon, QC Intxn to Atuko, QC Intxn

T107:Wabush, NL VOR to Pekro, NL Intxn to Goose, NL VOR

T201: William Lake, BC VORTAC to Heire, BC Intxn to Elidi, BC Intxn to Keinn, BC Intxn

Are these like victor airways, but using RNAV intersections instead?
