Continuing my work on Supreme Court data mining, I've extracted the firm names from the last ~7000 Supreme Court of Canada cases (going back about 10 years). This analysis was done by taking the first line of the address for each party, which is almost always the firm name. Below are the top 14 firms + the Attorney General of Canada.
|Firm Name||Party Count||Case Count|
|Gowling Lafleur Henderson LLP||3772||2437|
|Attorney General of Canada||1477||1224|
|Lang Michener LLP||1206||852|
|Noël & Associés||882||638|
|Supreme Advocacy LLP||670||464|
|Borden Ladner Gervais LLP||501||367|
|Osler, Hoskin & Harcourt LLP||297||183|
|Nelligan O'Brien Payne LLP||281||178|
|McCarthy Tétrault LLP||259||185|
|Fraser Milner Casgrain LLP||239||136|
|Sack Goldblatt Mitchell LLP||237||166|
|Heenan Blaikie LLP||227||141|
|Fasken Martineau DuMoulin LLP||227||149|
The Attorney General of Canada isn't a law firm but I've kept it in the table because I was surprised to see that they're not #1.
You'll notice in the above table that there's a "Party Count" and "Case Count". Party Count is the number of parties that the firm has represented. Case Count is the number of different Supreme Court of Canada cases they have been counsel to (it's lower because they sometimes represent multiple parties).
There may be some firms above that have slightly different counts if they provided their name to the Supreme Court in different ways although this kind of error only seems to occur for Lang Michener, which is listed sometimes as "Lang Michener" and other times as "Lang Michener LLP". The next 10 results aren't variant spellings of the above firm names so these numbers should be quite accurate.
