Dear @AirCanada CMO Dr Jim Chung and VP of Safety Samuel Elfassy

Thank you for the message “your safety and the safety of our employees is our top priority” inside every CleanCare+ package on #AirCanada flights. 🧵/10
I fly a lot with @AirCanada as it has more international destinations than any Canadian airline.

Prior to lockdowns that was about 1 week/month. Have the luggage tag to prove it.

I want to get to a point where we feel safe not wearing a mask on a plane. 2/10
However I would like to ask you some questions about safety on board Air Canada flights…

These questions are about 2 domestic flights within Canada AC157 and AC146

#COVID19AB #CovidIsNotOver 3/10
Why does the HVAC system get turned off when passengers board the plane?

What can be done to ensure that CO2 readings do not reach 4996 ppm when boarding the plane?

@AirCanada #CovidIsNotOver 4/10
Every CleanCare+ package provides 2 hand sanitizing gels, 2 antiseptic wipes, and a Guard branded non-surgical mask.

How can the CleanCare+ package align with the science that #COVIDisAirborne?

@AirCanada #COVID19AB 5/10
Can the Guard branded masks use a surgical band so they do not hold the sides of the mask open?

Crossing the band around my ears does not close the gaps because the band itself is lose compared to a surgical band.

@AirCanada #COVID19AB 6/10
My concern is that the card signed by the CMO of #AirCanada and the VP of Safety in every Clean Care+ package provides a false sense of safety.

@AirCanada
7/10
Passengers were using the masks with large gaps on the side, CO2 when boarding is extremely high, and ventilation systems are often not connected until the flight is in the air.

8/10
Would it help Air Canada staff to wear N95 masks to protect them against airborne diseases?

@AirCanada #WearARespirator #COVIDisAirborne 9/10
My hope with this is that we will get towards mask free safety on flights in the near future.

In flight is still 1700ppm on average, can we get closer to 600ppm so everyone is safe without masks?

@AirCanada #CovidIsNotOver 10/10

My friends have been trying hard to fight disinformation on WeChat this #AbElection2023

We did not want to share this because of the great shame it would bring to our community.

But everyone who #abvotes Monday should know the truth @ElectionsAB This propoganda will bring ...
A fake tweet claiming to be from @albertaNDP leader @RachelNotley was shared on several Alberta WeChat groups.

It positions Rachel as allowing kids access to gender affirming surgeries without parental consent.

This is false.
@ElectionsAB #AbElection2023 #abvotes A fake Rachel Notley tweet ...
The fake tweet has many mistakes obvious to native English speakers

proud as “pround”

“christian fascism”

Our province as “alberta”

“Enough is Enough”

“affirm their childs”

Learning a new language is hard so I don’t take issue with the text

The #UCP took the opinions of a physician and math researcher and turned it into the #AbEd math curriculum.

Literally the two in this article
ctvnews.ca/mobile/canada/…
If you don’t know what an unbounded norm convergence in a banache lattice is then you now understand the problem with the #AbEd Math Curriculum.

It wasn’t made by primary education teachers, it wasn’t designed for our kids.

Financial literacy that only introduces investing is harmful to our children.

There are many scams they will fall prey to if they can’t think critically about long-term value.

This is why investing requires more developmental growth. #AbEd

I had two professional COVID-19 antigen tests yesterday.

The London Test came back negative

The Toronto Test came back negative

Passengers coughing on the 4996 ppm CO2 @AirCanada flight

N99 mask on the whole flight with a Hepa filter on the whole time. No snacks…
Coughing today…

Took a RAT test

I tested positive for COVID-19.

Now I’m wondering how many others on AC157 got it as well.

#COVIDisAirborne #COVID19AB @AirCanada
Called 811, @AHS_media they told me they no longer do contact tracing.

Isolate for 5 days...

No PCR required to determine the variant.

No need to inform the 150+ passengers on the @AirCanada 157 flight that they might have COVID.

That's #COVID19AB

Record CO2 readings from a parked #AirCanada flight loading passengers.

This flight also did not turn on ventilation until the plane is in the air. That’s why temperature was 18°C while CO2 near 4K ppm.

Turn it on @AirCanada #CovidIsNotOver #COVID19AB
Auxiliary power unit failed, and it was too windy to hook up external power.

Captain says we will be flying with only one engine and hoping that the second engine will start afterwards so that we can run HVAC into the cabin.

🤞 How we fly #AirCanada in 2022
Good news: plane is warming up!

Bad news: HVAC is still not working

Congrats #AirCanada we have a new CO2 record
