PÉNAL (DROIT) : Dans une affaire de voies de fait graves commises à l’endroit d’une inconnue à la sortie d’un bar, en se limitant à énoncer les conséquences indirectes de la peine et en les qualifiant de facteurs neutres, sans les analyser véritablement dans l’exercice de détermination de la peine, . . .

A perpetual question from clients is whether a new development should be protected by filing a patent application or kept as a trade secret?

Patents are granted by national patent offices for new, useful and not obvious inventions. Patents require a full and public description of the idea and the details needed by a skilled person to put that idea into practice. For example, Section 27(3)(c) of the Patent Act requires that for machines, the patent “explain the principle of the machine and the best mode in which the inventor has contemplated the application of that principle”.

The new federal omnibus bill on the economy – Bill C-39, the Building Canada Strong Act – contains in Part 2 (“Keep Canada Moving”) Division 8, the Enabling Digital Trade Act.

This text implements for international trade in Canada the UNCITRAL Model Law on Electronic Transferable Records (MLETR). It allows, though does not require, the use of electronic versions of transferable records. Transferable records transfer title to the goods or sums mentioned in them by the transfer of the records themselves. Bills of lading are a common example, promissory notes another.

The provisions are a pretty straighforward reproduction of MLETR. . . . [more]

This is the final article in my series on RECLAIM, a cultural operating system for law firms. Having worked through Respect, Equity, Clarity, Learning, Autonomy and Inclusion, I finish with M for Meaning. You can find the full list of articles here.

I began this series in January 2026, in response to what I was reading about culture, and to hearing about law firms exploring culture at long last as an important part of their operations.

In strategic planning work with Carina Bittel, we have come to understand the relationship of culture to legal business this way: Strategy . . . [more]

One of the recurring themes of this column has been the extent to which the governance of artificial intelligence in Canada is increasingly being shaped by institutions outside the country while regulatory action within the country is largely stalled. Anthropic’s recent announcement that future versions of Claude will place an invisible watermark in generated text offers the most recent example of this phenomenon. A transparency requirement enacted in the European Union will alter the operation of Claude globally and may therefore leave a detectable signal in legal work prepared in Canada, including work produced through specialized legal-focused AI platforms that . . .

The Society for Children and Youth of BC (SCYBC) recently published a series of research papers on child capacity in the context of children’s participation rights [Note 1]. The papers examine capacity generally and in four specific contexts: health care, mental health, family law, and child welfare and adoption.

Why does this matter? Traditionally, we have tended to assume that a child must first demonstrate sufficient “capacity” before being permitted to meaningfully participate in decisions affecting their life. And capacity has often been assessed primarily through the lens of cognitive ability.

The SCYBC reports challenge both assumptions.

December 30, 2022 was a momentous day in Canada’s copyright history, although it may not have been on the radar of the majority of the Canadian public. That is the date that the term of copyright protection in Canada changed to align with that of the United States, a requirement of the Canada-US-Mexico (CUSMA) trade agreement that came into force on July 1, 2020. Previously, Canada had the shortest copyright term of the three North American countries: the life of the author plus an additional 50 years. The CUSMA agreement forced the extension of that term to life plus 70 . . . [more]
