I'm going to have to go ahead and respectfully ask Dr. Stanbrook to pull his head out of his .... Much of the data he cites is flat out wrong, and his way of looking at this issue is inside out.
The first and foremost duty of any doctor is to "Do no harm.". If even one smoker dies because they took his biased opinions to heart, someone that otherwise would have switched to vaping and lived, then he has failed utterly at his vocation.
I smoked 2 packs a day for over 25 years, actively trying to quit for 20 of them. Smoking was literally killing me (I have peripheral arterial disease), and still I couldn't quit. Three years ago I switched to vaping, and haven't touched a cigarette since my first kit came in the mail. There is a good chance that I'd be dead now if I hadn't switched.
If I had to wait 10 years for health Canada to approve these devices before I could use them, I'd be dead. I'm an addict, and I can live with that. What I can't live with is having arrogant misinformed zealots like the good doctor shape policies that have a direct impact on the quality and length of my life.
