Does the Arbitrator have to "explicitly address all possible shades of meaning" of contested provisions in their reasons?

Alberta, Canada


The following excerpt is from United Food and Commercial Workers, Local 401 v XL Foods Inc (Calgary Beef Plant), 2014 ABQB 704 (CanLII):

I recognize that the Arbitrator does not have to “explicitly address all possible shades of meaning” of contested provisions (as per Construction Labour Relations v. Driver Iron Inc. 2012 SCC 65 at para 3): This court has strongly emphasized that administrative tribunals do not have to consider and comment upon every issue raised by the parties in their reasons. For reviewing courts, the issue remains whether the decision, viewed as a whole in the context of the record, is reasonable.
