What our customers are saying

Our customers trust Westlaw for up-to-date, authoritative and actionable content that gives them bulletproof confidence. 

I rely on Westlaw to help me find helpful uncommon cases. In one recent sentencing hearing the judge commented that he was unaware of some of the cases I had cited. These cases clearly had a big impact on his decision, since he commented that “If your lawyer hadn’t done such excellent research and such an outstanding job, I would’ve given you 4 or 5 years.” To me, there is no substitute for thorough research, and for me that means Westlaw.

Lindsay Doucet, J.D. 
Mainwood Legal Services 

I became used to researching the law with hard-copy books … in the past few years, I’ve started using the leading online research system Westlaw …. It raises my confidence level that I’m totally on top of my game…

Bruce MacFarlane, Q.C. 

In practice, I use it on a near daily basis whether it is for researching statutes and regulations for various corporate matters or case law research for immigration appeals, refugee hearings or judicial review proceedings. Westlaw is great because there is guidance material available to help develop research skills, better understand search techniques and shortcuts and I personally have found that the more I use it and discuss with other lawyers I am constantly finding unique uses for the technology.
