3D Printed Models for Legal Cases

I think 3D printing is the future for cases that involve construction. Although insiders may understand floor plans, seeing a physical model of the building as it will be is powerful. Below are a few photos of a 3D printed model for a case that I recently worked on. It was the first 3D model that the expert planner, who's been in the business for 30 years, had seen (and they got a copy of the model too).

What Does A Bitcoin Lawyer Do?

My business cards say "Technology Lawyer" not "Bitcoin Lawyer" but Bitcoin-related work was approximately 60% of my legal practice last year.

In the last year I've spoken about Bitcoin and law in front of 300+ Canadian Corporate Counsel Association lawyers, a roomful of banking lawyers at the Canadian Institute's Payments Forum and at other smaller events. I'm often asked "what do you do for your clients?".

AI and Law: Looking Forward

Queen's Law held a panel discussion last week on the topic of AI and law. A recording of the discussion and a summary will be made available in the fall. In the meantime, here are my prepared remarks. The actual discussion ended up covering different ground than the questions that were distributed ahead of time and my fellow panelists had a lot to add. I'll post a link to the discussion when Queen's does.

The other panelists were Janet Fuhrer, Jeff Fung and Jordan Furlong. The moderator was Professor Cockfield with assistance from Lisa Graham and John Neufeld.

My Ideal Time-Tracking Software

I'd like a time-tracking service like Toggl (Internet-based and works well on mobile and desktop). But I'm a lawyer so I don't want to store confidential client information on a service like that, so it would need to be client-side encrypted. I'd also like the software to tell me about opportunities to generate additional business (i.e. make more money).

Client-side encryption can now be done on most browsers using the WebCryptoAPI (although implementation is a challenge for developers). My ideal service would encrypt all of my data client-side with AES and then upload it to the time-tracking system. When I access the service it decrypts locally to show me my information.

IRS & CRA Should Cheer for Uber

The CRA and IRS should be the biggest champions of the "sharing economy". Why? Because the sharing economy means the taxable economy.

Uber is solving a problem its founders never intended to solve that it gets no recognition for: untaxed taxi transactions.

Nintendo is taking another stab at using YouTube's Content ID system to claim part of the advertising revenue of "let's play" videos that feature its games: Where do content creators stand when it comes to Canadian copyright law and claims by video game companies?

Good Luck Starting a Bus Company in Ontario

If you want to start a bus line in Ontario you'll need to prove to the Ontario Highway Transport Board that your service will serve "public necessity and convenience" which includes, among other things, explaining your "impact on existing carriers if the service were granted". You also need to tell the board who are your "10 Largest Shareholders" and the "No. of Shares held" by each of them, your "business plan" and a "projected operating statement for the first year". After you file this information anyone in Ontario can request a copy ("All information pertaining to the applicant i.e. business plan, supporting evidence, etc. is on file at the Board and is available upon request." [e.g. on pg. 472]).

Bitcoin Meets the Stock Market: Legal Issues

Bitcoin is changing perspectives on how we manage assets. If money can be moved around instantaneously without friction then why not shares too? In 2015 shares are often digital abstractions traded through all-electronic stock exchanges. Bitcoin enthusiasts look forward to a world where banking, investment and securities companies are disintermediated and the world's savers can invest around the world without friction. But how does this new model for issuing stock fit within securities laws?

World's First Publicly Traded Bitcoin Exchange: QuadrigaCX

QuadrigaCX, Canada's dominant Bitcoin exchange, is set to become the world's first publicly traded Bitcoin exchange according to Bitcoin Magazine. I don't see the news reported anywhere else (including on Quadriga's own site/Twitter) but Christie Harkin, the author of the article is a good source.

This is pretty big news for a Canadian company that only started a little over a year ago. Up until this year there were three exchanges competing for Canadians' wallets but as of mid-February there's only Quadriga. Given that the gross margins on Bitcoin trading are ~0.5%, Quadriga is probably still standing due to their cost structure being lower than their former competitors.
