This area is very competitive, and generally requires competitive grade and TOFEL score. In Canada, most universities only require TOFEL score for international students.
University of British Columbia (www.ubc.ca) has two faculties offer the program your friend is looking for. I am not an expert in the filed. I don't know which program will fit your friend. Please take a look at the follwoing two programs and make your own judgement:
- Pharmaceutical Sciences (by Faculty of Pharmaceutical Science)
- Pharmacology and Therapeutics (by Faculty of Medicine)
Both program requires 600 TOFEL score for paper test, and 250 TOFEL score for computer test.
