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].

Canada’s wealth is based on its success as a trading nation. Canada is blessed with immense resources spread across a vast country. It has succeeded as a small, open economy with an enviable standard of living that has been able to provide what the world needs.
Canada has been stuck in a situation where it cannot complete nation‑building projects like the Canadian Pacific Railway that was completed in 1885, or the Trans Canada Highway that was completed in the 1960s. With the uncertainty of U.S. tariffs looming over our country and province, Canada needs to take bold action to revitalize the productivity and competitiveness of its economy – going east to west and not always relying on north-south trade. There’s no better time than right now to politically de-risk these projects.
A lack of leadership from the federal government has led to the following:
- Inadequate federal funding for trade infrastructure.
- A lack of investment is stifling the infrastructure capacity we need to diversify our exports. This is despite federally commissioned reports like the 2022 report by the National Supply Chain Task Force indicating the investment need will be trillions over the next 50 years.
- Federal red tape, like the Impact Assessment Act.
- Burdensome regulation has added major costs and significant delays to projects, like the Roberts Bank Terminal 2 project, a proposed container facility at Vancouver, which spent more than a decade under federal review.
- Opaque funding programs, like the National Trade Corridors Fund (NTCF).
- Which offers a pattern of unclear criteria for decisions and lack of response. This program has not funded any provincial highway projects in Alberta, despite the many applications put forward by the Government of Alberta. In fact, we’ve gone nearly 3 years without decisions on some project applications.
- Ineffective policies that limit economic activity.
- Measures that pit environmental and economic objectives in stark opposition to one another instead of seeking innovative win-win solutions hinder Canada’s overall productivity and investment climate. One example is the moratorium on shipping crude through northern B.C. waters, which effectively ended Enbridge’s Northern Gateway proposal and has limited Alberta’s ability to ship its oil to Asian markets.
In a federal leadership vacuum, Alberta has worked to advance economic corridors across Canada. In April 2023, Alberta, Saskatchewan and Manitoba signed an agreement to collaborate on joint infrastructure networks meant to boost trade and economic growth across the Prairies. Alberta also signed a similar economic corridor agreement with the Northwest Territories in July 2024. Additionally, Alberta would like to see an agreement among all 7 western provinces and territories, and eventually the entire country, to collaborate on economic corridors.
Through our collaboration with neighbouring jurisdictions, we will spur the development of economic corridors by reducing regulatory delays and attracting investment. We recognize the importance of working with Indigenous communities on the development of major infrastructure projects, which will be key to our success in these endeavours.
However, provinces and territories cannot do this alone. The federal government must play its part to advance our country’s economic corridors that we need from coast to coast to coast to support our economic future. It is time for immediate action.
Alberta recommends the federal government take the following steps to strengthen Canada’s economic corridors and supply chains by:
- Creating an Economic Corridor Agency to identify and maintain economic corridors across provincial boundaries, with meaningful consultation with both Indigenous groups and industry.
- Increasing federal funding for trade-enabling infrastructure, such as roads, rail, ports, in-land ports, airports and more.
- Streamlining regulations regarding trade-related infrastructure and interprovincial trade, especially within economic corridors. This would include repealing or amending the Impact Assessment Act and other legislation to remove the uncertainty and ensure regulatory provisions are proportionate to the specific risk of the project.
- Adjusting the policy levers that that support productivity and competitiveness. This would include revisiting how the federal government supports airports, especially in the less-populated regions of Canada.
To move forward expeditiously on the items above, I propose the establishment of a federal/provincial/territorial working group. This working group would be tasked with creating a common position on addressing the economic threats facing Canada, and the need for mitigating trade and trade-enabling infrastructure. The group should identify appropriate governance to ensure these items are presented in a timely fashion by relative priority and urgency.
Alberta will continue to be proactive and tackle trade issues within its own jurisdiction. From collaborative memorandums of understanding with the Prairies and the North, to reducing interprovincial trade barriers, to fostering innovative partnerships with Indigenous groups, Alberta is working within its jurisdiction, much like its provincial and territorial colleagues.
We ask the federal government to join us in a new approach to infrastructure development that ensures Canada is productive and competitive for generations to come and generates the wealth that ensures our quality of life is second to none.
