From the law firm of Faskin Martineau (via Wise Law):

Canada is more litigious than most believe, according to a study commissioned by leading Canadian law firm Fasken Martineau. Over 40% of respondent companies indicated they were involved in some form of litigation over the prior year.

Labour and employment issues rank the highest in the type of dispute that most concerns Canadian companies according to the Fasken Martineau study. Contracts, personal injury and product liability rank second, third, and fourth, respectively.
