IMPORTANT NOTE: You should be familiar with the scope of the coverage periods used by any of the services you use for noting-up case law. Here is a comparative table which compares KeyCite and QuickCITE coverage periods:

KeyCite coverage QuickCITE coverage
KeyCite commenced coverage of judicial consideration of appellate unreported cases in 1987, and all superior court cases in 1992. Originally QuickCite did not cover unreported decisions dated prior to 1993. More recently, decisions are being added that pre-date 1993.
For cases before 1987, KeyCite may not include cases that merely refer to the cited case. QuickCite includes cases that merely refer to the cited case.
KeyCite has excellent historical coverage, starting in 1867. Originally QuickCite's coverage did not start until 1940, except for decisions of the Supreme Court of Canada and Privy Council. More recently, decisions are being added that pre-date 1940.
KeyCite adds citing cases more quickly than QuickCite, but they do not have a treatment code assigned when first added. QuickCite includes judicial consideration by courts of board and tribunal decisions released after 1994.

KeyCite is designed to quickly tell you whether a case is good law, through status flags, organising results by treatment code, and grouping case history with negative treatment. Results can also be customized in several ways including by court level, date, jurisdiction, and type of consideration. QuickCite results first show a summary of treatments for the case. The citing cases are shown by default in reverse chronological order. They can be easily sorted and filtered in various ways, including by jurisdiction, by court, by level of court, by date, and by negative or positive treatment.
KeyCite allows refinement of results by conducting a keyword search within the KeyCite results. QuickCite does not permit refinement by keyword.
KeyCite includes references to secondary sources that have considered the case. QuickCite results do not include secondary source references.
