In Canada the design code is CSA S304.1-04. The Canada Masonry Design Centre has a design handbook title "Masonry Structures, Behaviour and Design" which has everything you should need for typical masonry applications (and some atypical).
The other reference I would have is "Masonry Design for Engineers and Architects" by Hatzinikolas and Korany which is the masonry version of the Kulak and Grondin book "Limit States Design in Structural Steel". Great references to have if you design in Canada.
