Calgary <-> Toronto 100% Canadian Fibre Resiliency on failover

Hi, Does anyone know if there's fibre resiliency between Calgary and Toronto over the Great lakes, I thinking redundancy could be achieved by using two paths one following the railroad and the other following the Trans-Canadian highway. Does anyone know if there is fibre following the Trans-Canadian highway and who owns it? Is this achievable? Thanks, Jacques CTO, CIRA
