Open Letter to Physicians and the Public of Alberta
Dear Dr. Hinshaw,
Re: Alberta Health recommendation that Albertans wear N95, surgical or non-medical masks in public to reduce the likelihood of transmitting or developing a condition from the coronavirus known as COVID-19
I have been teaching and conducting respirator fit testing for over 20 years and now currently for my company SafeCom Training Services Inc. My clients include many government departments, our military, healthcare providers with Alberta Health Services, educational institutions and private industry. I am a published author and a recognized authority on this subject.
Filter respirator masks, especially N95, surgical and non-medical masks, provide negligible COVID-19 protection for the following reasons:
- Viruses in the fluid envelopes that surround them can be very small, so small in fact that you would need an electron microscope to see them. N95 masks filter 95% of particles with a diameter of 0.3 microns or larger. COVID-19 particles are .08 – .12 microns.
- Viruses don’t just enter us through our mouth and nose, but can also enter through our eyes and even the pores of our skin. The only effective barrier one can wear to protect against virus exposure would be a fully encapsulated hazmat suit with cuffs by ankles taped to boots and cuffs by wrists taped to gloves, while receiving breathing air from a self-contained breathing apparatus (SCBA) This barrier is standard gear to protect against a biohazard (viruses) and would have to be worn in a possible virus hazard environment 24/7 and you wouldn’t be able to remove any part of it even to have a sip of water, eat or use the washroom while in the virus environment. If you did, you would become exposed and would negate all the prior precautions you had taken.
3. Not only are N95, surgical and non-medical masks useless as protection from COVID-19, but in addition, they also create very real risks and possible serious threats to a wearer’s health for the following reasons
A. Wearing these masks increases breathing resistance, making it more difficult to both inhale and exhale. According to our Alberta government regulations on respirator (mask) use, anyone that is required to wear a respirator mask should be screened to determine their ability to safely wear one.
Any covering of the mouth and nose increases breathing resistance, whether the mask is certified or not. Those individuals with pre-existing medical conditions of shortness of breath, lung disease, panic attacks, breathing difficulties, chest pain in exertion, cardiovascular disease, fainting spells, claustrophobia, chronic bronchitis, heart problems, asthma, allergies, diabetes, seizures, high blood pressure and pacemakers need to be pre-screened by a medical professional to be approved to be able to safely wear one. Wearing these masks could cause a medical emergency for anyone with any of these conditions.
Pregnancy-related high blood pressure is possible. More research is necessary to determine the impact of wearing a mask for extended periods of time on pregnancy.
It is dangerous to recommend, much less mandate anyone with medical conditions to wear a mask without educating them about the risks involved in wearing them without having been pre-screened and approved by a medical professional first.
B. In order for any respirator mask to offer protection to a specific user, that user must be individually fitted with the right type, right size, if male – face must be clean shaven (only short moustache allowed). Next, the user must be fit tested with that respirator by a trained professional to determine whether or not the respirator is providing the user with an air- tight seal – a requirement for any respirator mask.
C. N95 masks – N for not resistant to oil particles, 95 for the percentage of protection – the lowest level of all respirator masks.
These masks even when properly sized and fitted will not protect against virus exposure, however they are capable of adequate protection from larger particles such as pet dander, pollen and sawdust.
Surgical masks (the paper ones that loop around the ears) – do not seal to the face and do not filter anything.
Nonmedical and/or homemade masks are dangerous because:
- ● Not engineered for the efficient yet protective requirements of easy inhalation and effective purging of exhaled carbon dioxide
- ● Could cause an oxygen deficiency for the user
- ● Could cause an accumulation of carbon dioxide for the user
- ● Shouldn’t be recommended under any circumstance
D. They increase body temperature and physical stress – could cause a high temperature alert on a thermometer gun
E. They impede verbal communication
F. N95, surgical and nonmedical masks can create infections and possible disease all by themselves by causing exhaled warm, moist air to accumulate on the inside material of the mask, right in front of the user’s mouth and nose, which is the perfect environment for bacteria to form, grow and multiply. That is why N95 and other disposable masks were only designed to be short duration, specific task use and then immediately discarded.
So if masks are not effective in preventing illness, what is? How about the age-old tried, tested and proven method of protecting our health with a healthy diet, clean water, avoidance of processed, junk and fast foods, plenty of fresh air, sunshine, moderate exercise, adequate restful sleep and avoidance of stress?
We all have an immune system that can fight and overcome any COVID-19 threat if it is healthy and we nurture it.
Thank you for reading this open letter and letting me share my expertise. I ask that you share this with the public via media statement as we are all committed to promoting good health for all Albertans. If you or any of the public wish to contact me with a question or comment, I would love to hear from you. I can best be reached [email protected].
Sincerely,
Chris Schaefer

On the hunt for a rental home in Calgary over the last six weeks, Marissa Giesinger and her boyfriend trawled through listings morning, noon and night, only to find most come along with dozens of applications and a steep price tag. As an added difficulty, many landlords are unwelcoming to the couple’s brood — dogs Kado and Rosco and a cat named Jester.
“We made the tough decision recently to house our dogs with someone else until we can find a place that’s affordable and we can take both of them,” said Giesinger, a 23-year-old Mount Royal University student.
“It’s definitely been stressful.”
The competitive rental market Giesinger has encountered in Calgary is being seen across the country as multiple factors combine: high interest rates deter buyers and add to rental demand, still-high inflation is squeezing renter budgets, there’s an undersupply of purpose-built rental units and population growth is fuelling demand.
These conditions have left prospective renters feeling even more frustrated than usual by sky-high rents, the frenzy of interest that surrounds any affordable listing and the litany of demands landlords can make when so many people are interested in their home.
Giacomo Ladas, communications director for Rentals.ca, calls it “almost a perfect storm” — and it isn’t likely to ease up any time soon.
“What this does is create such a burden on this rental housing market that even though we’re out of the (busy) summer rental season, there’s so much demand that (these conditions are) going to continue like this until the fall and into the winter,” he said.
Data crunched by his organization and research firm Urbanation.ca shows average asking rents for newly-listed units in Canada increased 1.8 per cent between July and August and 9.6 per cent from a year earlier to reach a record high of $2,117 last month.
Between May and August, asking rents in Canada increased by 5.1 per cent or an average of $103 per month.
When Giesinger rented a two-bedroom basement unit with a roommate a few years ago, the duo paid $1,000 per month, but now she routinely spots “super tiny,” one-bedroom places for $1,350 a month.
“If you want a basement suite or an apartment, you’re looking at minimum $1,200 and that doesn’t include any utilities or anything like that unless it’s a super rare listing,” Giesinger said.
Rentals.ca data show newly listed one-bedroom properties in Calgary priced at an average $1,728 per month in August, up 21.6 per cent from a year earlier. Two-bedroom homes have climbed 17.4 per cent to $2,150 over the same period.
The picture in Vancouver and Toronto is far bleaker. Rentals.ca found the cities had the highest rents in the country.
Newly-listed one-bedroom properties in Vancouver averaged $2,988 in August, up 13.1 per cent from a year earlier, while two-bedroom units hit $3,879, an almost 10 per cent increase year-over-year.
Newly-listed Toronto one-bedroom homes averaged $2,620 in August, up almost 11 per cent from the year before, while two-bedroom properties had a 7.1 per cent rise over the same time frame to $3,413.
It’s numbers like these that have convinced Kanishka Punjabi to abandon her hopes of moving in the near term.
“Two days ago, I gave up on my search because the rental market is that bad,” she said.
The public relations worker has been living in Mississauga, Ont., but felt it was time to find a home in downtown or midtown Toronto, closer to where she works.
However, few of the two-bedroom homes she spotted in her two-month search were within her $2,800 budget.
For example, one apartment she liked at the intersection of Yonge and Eglinton streets had 25 offers in just over a week.
“Some people actually just sent in their offer without looking at the apartment too because there are so many people who are in desperate need of rental units,” said Punjabi. “There’s just not enough.”
The Canada Mortgage and Housing Corp. has projected that the country needs to build 3.5 million additional homes beyond what’s planned before the market reaches some semblance of affordability.
It also calculated that the annual pace of housing starts — when construction begins on a home — edged down one per cent in August to 252,787 units compared with 255,232 in July.
Despite the nudge down, Rishi Sondhi, an economist with TD Bank Group, said it has been a strong year for starts because the industry is responding to elevated prices by building at a robust pace.
But between population growth and rising interest rates, he said, “supply is struggling to keep up with demand” and that’s bound to weigh on renters for quite some time.
“In the short term, it would be unrealistic to expect too much of a reprieve simply because population growth is likely to remain strong through the duration of this year — and that’s really one of the big fundamental drivers,” he said.
“In addition, it’s unlikely to expect affordability in the ownership market to improve too much either because we think the Bank of Canada (key rate) is going to be on hold for the remainder of the year, but there is some risk that they take rates even higher, especially if inflation doesn’t co-operate.”
For renters like Giesinger that message puts even more pressure on her to settle on a place soon.
“Now I’m scrambling to find the money for a deposit and we’re still never really sure like what kind of place we’re going to get,” she said.
“And when you’re battling dozens of other people for a rental it can be super stressful.”
