I stand corrected.  My mistake. The North / South route or road has been called a "Corridor" before.  But not by Marten Falls, who consider it a road to connect with the provincial highway....and apparently the East / West corridor is cheaper than the North / South corridor, because of the number of river crossings the North / South has.  Sorry if my comments were misleading. After making the comments I felt compelled to question whether my information was correct. 

In searching past articles I came across this one below, which corrects what I had said about the E/W vs N/S corridors or routes. I believe my confusion about N/S road/route vs corridor came through Marten Falls repeatedly referring to their connection to the main highway as a "Community Access Road".  Again, my apology.  I still standby the Mushkegowuk plan being the best option. 

This being said I would like to change my initial remark and state that  Mr. Rickford may be using a past Liberal reference to the North / South route/road connecting to the main provincial highway as a "Corridor".  The "Corridor to Prosperity" I believe he was referring to at the "Meet the Miners" conference is the "N/S Corridor", which has a Marten Falls "Community Access Road" attached to it; source of confusion.

Quotes from above article: 

.......One isolated First Nation community near the Ring of Fire declares that a year-round access road will bring a "prosperous, sustainable, and more inclusive future for its elders, youth and families."........

In an Aug. 31 news release, Marten Falls said the time has come to finally be connected to the provincial highway system after "years of negotiating and planning" for a community access road.

But Marten Falls is signaling it's only too willing to work with the province in planning and building a north-south road.

......."Marten Falls sees this as an opportunity for present and future generations of families who want to live in the community and be gainfully and proudly employed. At the same time, this is also an opportunity for other regional and remote First Nations to connect with the north-south corridor and participate in related socioeconomic benefits," said the community release........

.....An east-west road, that basically followed the established winter road network, was considered a cheaper alternative to reach the Ring of Fire than a north-south corridor, which would have to cross major river systems......
