Will was a joint recipient of the Department of Justice National Award for his work in resolving the high-profile Maher Arar v Canada case. He has also been honoured by the University of Toronto for many years of volunteer efforts on behalf of his alma mater.

Instructions to Spies: Are They Privileged?
In brief, the decision by Justice Boswell of the Commercial List suggests that solicitor/client privilege has been narrowed, and litigation privilege has become easier to lose. For seven years, Catalyst Capital and West Face Capital have been at war. Their latest skirmish, over privilege, might change the way that lawyers interact with witnesses, investigators, and the media.

In 2017, the Canada Food Inspection Agency (the “CFIA”) determined that wines produced by Psagot Winery, a vineyard located within an Israeli settlement in the West Bank, could be sold in Canada with a “Product of Israel” label to meet “country of origin” labelling requirements required under the Consumer Packaging and Labelling Act and the Food and Drugs Act. This decision was challenged by Dr. David Kattenburg, a Canadian activist, on the basis that the wine was in fact produced on occupied Palestinian territory and not within Israel, making the labelling of “Product of Israel” false and misleading and therefore contrary to the applicable legislation.

Supreme Court of Canada Provides First Guidance on the Test for an Anti-SLAPP Motion
The Supreme Court of Canada has released its highly anticipated pair of decisions, 1704604 Ontario Ltd v Pointes Protection Association and Bent v Platnick, which consider the anti-SLAPP framework set out in s 137.1 of the Ontario Courts of Justice Act (“CJA”) for the first time.
-
When Must an Anti-SLAPP Motion Be Heard?
Ontario’s Anti-SLAPP legislation (ss 137.1 to 137.5 of the Courts of Justice Act) provides a judicial screening device. It is designed to swiftly eliminate claims that unduly limit freedom of expression on matters of public interest. Since coming into force, courts have considered, at length, the substantive issues. To date, little guidance has been provided on the procedural issues.
