I have to go with insulin. A brilliant pharmacologist I worked with has type 1 diabetes. He worked his whole career to develop and research life saving heart arrhythmia treatments. Insulin saved his life and the lives of countless others who contribute to the betterment of humanity.

A no brainer. INSULIN continues to save lives. Though gone by the wayside Blackberry Northern Telecom's Phone Switches

I'd have to say insulin. A game changer for millions of people.

Polio vaccine from the same place insulin came from. Connaught labs. U. of T. and now Sanofi. Connaught Medical Research Laboratories was a non-commercial public health entity established by Dr. John G. FitzGerald in 1914 in Toronto to produce the diphtheria antitoxin.

Insulin! The others are, to some or all extent , only conveniences or entertainments- insulin actually saves lives and took a few folks years to invent!

Insulin

All fabulous inventions, however, insulin is one people cannot live without.

James Naismith, the inventor of basketball, was Canadian born, but developed the game while living in Massachusetts, and later coached for the University of Kansas. The US and Canada were close friends for generations, and I hope that after we kick Trump's ass to the curb, we can be friends again.🇺🇸🇨🇦

Insulin. Not just because it continues to save lives, but because they literally gave the patent away. Sold for just $1 so that it could save millions of lives. Before insulin, those with type 1 diabetes had a life expectancy of less than 3 years.

Insulin and it’s not even close. (Poutine comes second.)

👆 That one... ...and this one. 👇

🫠 OK... but I didn't say anything about fries, did I? What I said was: "Belgians (as far as anyone knows with any certainty) have never invented anything of note." I can't imagine even feigning interest in a museum exhibit focused on fried potato. 🍟

Insulin, please see the reasons above.

Insulin, and also the Robertson screw.

You are so, so right.

Insulin with the electric wheelchair running a close second — I use both, but the insulin is life-changing or even life-saving.

As a diabetic hands down it is insulin... without it i might not be alive today!

Insulin, without a doubt

Insulin has saved a lot of lives around the world. However…. UN peacekeepers (Canadian idea) have too!

Insulin hands down because it saves lives.

The answer is insulin but I'm noting the egregious absence of the Robertson screw.

Insulin. But I wanted to say Canadarm.
