At my university (Dalhousie, Halifax NS), they still use Java for the first 3 classes (CSCI1100,CSCI1101,CSCI2110) which are basic data structure and algorithm classes, they include a mixture of Linked Lists, Binary Trees, Search Algorithms, etc. Afterwards its a mixture of C, C++, Matlab, Perl, and Scheme.

Generally the more mathematical based courses like Digital Signal Processing use MATLAB, Operating Systems and Algorithms in C, Graphics (Computer Graphics, Animation, etc) in C++, Object Orientated Programming in C++, and Principles of Programming Languages (Compiler Design, Grammars, Scoping etc..) in Scheme and C/C++.

All other courses give the student free reign on what language they choose. It's interesting to note that atleast from my year there seems to be a uniform distribution of C#,C++,Java,Python, and Perl used in these courses. They tend to be the more project based such as Information Retrieval, Network Computing, Software Engineering etc.

However, a large amount of the faculty no longer supports Java as the language that is taught in first year computer science (Java and C are the only languages that are taught in class at all) and moving towards Python after they have had great success in the last several years with intro courses for non-cs majors.
