I've written a series of programs that process and extract the names of counsel from Ontario Court of Appeal judgements. I've analysed 8077 decisions and extracted 12,000 lawyer-case pairs (some decisions have multiple counsel).

Using the extracted data I compiled a table of the lawyers who appeared most frequently before the Court of Appeal over the last 15 years.

You'll see below the names and numbers of cases that each lawyer has worked on. If you click the name you'll see a list of the cases with year, role of the lawyer (appellant/respondent) and a link to the case.
