There's a group at McGill University doing a survey on English word usage in Canada. All you have to do is email them at canadian_english@mcgill.ca

At the bottom of the form I received it notes the survey may be returned to : Prof Charles Berg, Dept of Linguistics, McGill University, 1085 Dr. Penfield, Montreal, QC, H3A 1A7 Canada -- Tel (514) 398-4896 -- FAX : (514) 398-7088 -- E-Mail : charles.boberg@mcgill.ca
I took it, so did a couple of my neighbors, my son and the young gal who comes in to help around the house. Some interesting differences and similarities! Age range from early 20s to me in 70s!
