Our theme is to empower; the goal is self-reliance. An ancient, intuitive proverb sums it up: If you give a man a fish, you feed him for a day; but teach a man to fish, and you feed him for a lifetime. The Latin phrase Tuum Est means It is up to you – an echo of the struggle faced by myself and many others with chronic disease or physical disability.

Tuum Est is an educational website which provides:

  • Information regarding the legal rights of physically disabled persons.
  • Guides to help you learn and negotiate the Canadian medical system.
  • Comprehensive resources for three uncommon autoimmune diseases:
    • Guillain-Barre Syndrome  (GBS)
    • Reflex Sympathetic Dystrophy  (CRPS Type I)
    • Interstitial Cystitis  (IC)

Share Your Experience

Send emails to share your story, to vent, to comment, to ask questions or offer suggestions, to discuss encounters with disability stereotypes, or just to connect with someone whose journey mirrors your own.

I plan to develop a section on my site devoted to stereotypes directed at the physically disabled. It would be useful to map the nature of each stereotype, how firmly those stereotypes are entrenched, and whether they change across different regions of Canada.

I reply to most emails, but time constraints mean I cannot advocate for people on an individual basis. Your name, email address, and the experience you describe will not be published nor alluded to on my site without your express permission. You will find further details in our Tuum Est Privacy Policy.

Our page Privilege: Exceptions and Exclusions is a general treatise, but – don't worry – the conclusions have applied to only one reader since Tuum Est was founded in 2008.

My musical instrument was the Highland Bagpipes. For a decade I marched as Pipe Sergeant of the Bonnie Bluebells Pipe Band in Saskatoon. At every celebration, the city asked us to parade in our kilts of Ancient Sutherland tartan, playing sprightly Scottish strathspeys, reels, and slow-airs. In solo competition, my Piobaireachd trophies took pride of place on my mantlepiece, as I love this classical music. My sport was Judo at the level of green belt (4th kyu).

My education includes two university degrees in Physics. At the University of British Columbia, my thesis research, titled Non-Linear Resonant Photoionization, used tunable lasers as the experimental tool and non-linear optics as the theoretical foundation. My thesis was written under my maiden name Petty, as were my publications in Physical Review Letters and the Canadian Journal of Physics.

After graduation I worked full-time as a research scientist until I developed a series of serious uncommon autoimmune diseases (Guillain-Barre Syndrome, Reflex Sympathetic Dystrophy, and Interstitial Cystitis).

As a hobby, I constructed logic and math puzzles. A handful of my early puzzles are online, for example Bumper Crop.  When time permits, I will publish on Tuum Est new, original puzzles in the categories of word logic, figure logic, and brain teaser. Difficulty level: one-star (easy) to five-star (expert). Enjoy thinking in three dimensions? Try Cubism. For logic in rhyme, my newest puzzle, go to The Cubist Painter. For other creative writing, explore Reflections.


There is a difference between providing a research service (which I can do) and giving legal advice or medical advice (which I cannot do). To give advice means to list all known options and recommend which option you should choose. That would require access to your full legal file or medical chart, plus a diploma in law or medicine.

Note: Tuum Est is pronounced toom est.
