If CRA needs to contact you, they do not send the content of your concern, they post the content to your account and notify by email that you need to login and read the content. This avoid exposing your personal information in email. So they care about security.
It is probably ok to use SMS passcodes for social media and other amusements where money is not involved. However, billions of dollars flow through CRA which is an attraction for bad-actor hackers. And hackers have tools to capture SMS codes while logging in as you. Cell phone networks have security bugs so information passing through them needs to be encrypted. This can't be done with SMS which is plain text.
Google "risk of sms for authentication" and it's all bad news. The best advice is don't use SMS for 2FA/MFA. It actually weakens security for CRA business.

Since golf clubs are opening soon, the Leafs went on vacation and brought in some beer-league look-alikes to take their place in the playoffs. Just kidding.
The Canadiens could beat the Leafs because they are a big, determined team backed by a super goalie and that team could defend the entire ice rink. They gave the Leafs little time and space to make plays. It does not matter what skill the Leafs have unless they have an answer to whatever tactics the other team tries. I only watched a part of game 7 and I saw a lot of small mistakes. Generally, the Leafs were slow and clumsy as if they were in an unfamiliar environment . Playoffs require a special energy, not just skill.
It is insane to bring in high-salary players just to repeat the games of old. The Maple Leaf organization needs a fresh perspective starting with a name change to one that suggests energy or power. Consider names like Lightning, Avalanche, Bruins, Golden Knights, or Jets. They have energy to blow away the wimpy Leafs. How about a name like Toronto Tornadoes.

Got the Pfizer jab for covid19 yesterday. The clinic was in a sports complex and was very well organised. It took 10 minutes to walk through the various check points, get the jab, and then linger for fifteen minutes in case of shock. I was pleasantly surprised given that there has been much grumbling and frustration concerning the vaccine rollout. This whole week was fully booked as soon as the online portal opened last week but I was lucky to see a few slots open when I made a random check this week. However, only two percent of Ontario people have been vaccinated and another lockdown is looming.

The displays of phones and computers have thousands of red-green-blue LEDs. All these LEDs are emitting to produce white which is the default color for web pages. The blue component is not good for your eyes.
The blue in sunlight provides some healthy stimulation during the day but humans did not evolve to live in constant blue light. So we should minimise exposure to device screens after sundown so that relaxation and a good night's sleep will follow.
The Kindle does emit some blue light but it is much less intensive than the blue level from phones and tablets.
