Proper way to run and fish electrical wire in Canada?
Another option is run EMT conduit across the bottom of joists.   EMT can be used in one of two modes: 


as a simple protective shield for the Romex style cables.  In this case, contemplate larger conduit diameters such as 3/4" for a single cable or 1-1/4" to 1-1/2" for multiple cables. The "conduit fill rules" require fairly large pipe when flat Romex is involved, because it can't be counted on to lay flat.  In this case you do not need steel boxes at the end of the conduit run, but the end of the run needs to be protected.  
as the Conduit Wiring Method, requiring steel junction boxes at both ends.  In this case you can pull cables through large conduit as above, but instead, may make a splice inside the junction boxes to wires more appropriate to the Conduit wiring method. 


The EMT Conduit Wiring Method is a great way to wire, when you are able to do it.  You don't need a ground wire (the EMT is the ground) and you can run individual THHN type wires, which also can be stranded wire, for much better handling and flexibility.  It allows you to carry as many as 4 circuits inside a 1/2" pipe.  

In any case, if several circuits are running together in a conduit pipe or simply bundled together for 600cm or farther, assure there are no more than 3 circuits together.   However 4 circuits is allowed if all of them are #12 (20A) or smaller. 

If you ever envision having 3 or more circuits, make the steel boxes at the end of the conduit run be 4-11/16 (120mm) boxes that are 55mm deep.  That provides enohgh space for up to 4 circuits worth of splices.
