It is straightforward to find out out how a Canadian case has been subsequently treated by Canadian courts; all you need to do is note it up on Quicklaw, WestlawNext Canada, or CanLII. However sometimes you need to find out if a US case has been mentioned in the Canadian case law and this is slightly more challenging to do.
The easiest way to note up a US case in the Canadian case law is by a Boolean search for the names of the parties and any citations for that case. For example, if you were trying to find out what Canadian cases had referred to Hiscott v. General Electric Co. (1975), 521 F. 2d 632, you might use the search string (Hiscott /4 General) OR “521 F. 2d 632”.
Depending on how common the names of the parties are, you may have to make the names used in your Boolean search more specific.
