Partnership is basically off the table. Many colleagues who have left have gone to other firms (if <5 years of call) and government/in-house if more senior. Most Canadians from Canadian law schools tend to go back to Canada. They usually land at the top litigation boutiques, good government posts, or outside of the practice of law.
Perhaps Uriel can help to answer this question, but I've heard that the partnership tract is easier to achieve in Canadian big law over US. Can anyone shed some light on what the reasons for this may be? Is it due to the structural differences in firms? The amount of $$ paid to associates in NYC? The nature of the work? Culture?
