COVID‑19 Toolkit

This guide is designed to provide support for occupational health and safety (OHS) management in the workplace. The information it contains is based on the recommendations made by the Directeur national de santé publique (DNSP), the Réseau de santé publique en santé au travail (RSPSAT) and the Institut national de santé publique du Québec (INSPQ). The guide specifies the CNESST’s expectations with regard to these recommendations. 

The measures proposed must be adapted to the different sectors to ensure that activities can resume or continue under the safest and healthiest possible conditions during the COVID-19 pandemic.

During a crisis, it is important that workers and other stakeholders work together to ensure healthy and safe workplaces for all. Dialogue and cooperation are essential to achieving this.

For the measures applicable to their clientele, workplaces should refer to the Direction générale de la santé publique guidelines

Management of occupational health and safety 

Management means implementing the necessary measures to honour the employer’s legal obligations, namely identify, correct and control the risks and encourage the workers’ participation in this preventive approach. 

Good cooperation between the employer and the personnel, including the members of the health and safety committee, as applicable, is crucial to promoting management of OHS. The workers’ representatives, particularly the members of the health and safety committee, as well as the prevention representatives, as applicable, can help identify everyday risky situations, evaluate the real feasibility of the actions envisioned, encourage their implementation and anticipate practical questions. They can also participate in dissemination of the information to their co-workers. When a health and safety committee is present, it would be expedient to analyze the possibility of adjusting the frequency of the meetings to the context of the work environment. 

It is also important to inform the suppliers, subcontractors, partners and customers of the measures implemented in relation to COVID-19 and the importance of compliance with these measures, and to solicit their cooperation. 

The result of the preventive approach allows proactive intervention when planning a safe resumption or continuation of operations while honouring the legal obligations. This also allows updating of the prevention program, as needed. 

After identifying the risks related to contamination in the context of COVID-19 in your work environment, it is important to implement the preventive measures recommended by the public health authorities and the occupational health and safety experts

When the preventive measures are chosen and implemented, it must be ensured that they remain in place and effective. This is called “permanency of corrective action”. In addition to applying the preventive measures specific to COVID-19, the employer must also consider the other risks related to his usual operations, new operations and ad hoc operations (e.g. work reorganization, restoration of machines to operation, maintenance, verifications). 

To propose specific tools to identify the risks and the preventive and control measures in the context of COVID-19, the CNESST has provided quick references and checklists to support the work environments in the management of occupational health and safety. 

Transmission mode

Coronaviruses generally affect the nose, throat and lungs. They usually spread through droplets in the air when you come into contact with an infected person, whether or not that person has symptoms. They can also be spread by contaminated hands. Thus, touching your mouth, nose or eyes after having been in contact with an infected person or a contaminated surface is a way of developing COVID-19. 

Coronaviruses will last a few hours on inert objects with dry surfaces and a few days on inert objects with moist surfaces. 

Preventive Measures

The employer must proceed with identification of the risks of transmission of COVID-19 in the work environment. If the risks of contamination cannot be eliminated, the employer must seek to reduce and control them. It must determine during which tasks workers are likely to be exposed to the virus.

Preventive measures may be applied to reduce the risks of transmission of COVID-19. They are based on the principles of exclusion of symptomatic persons from the workplace, physical distancing, hand hygiene, respiratory etiquette and maintenance of hygiene measures for the tools, equipment and frequently touched surfaces.

Exclusion of symptomatic workers from the workplace 

Persons exhibiting symptoms are part of the COVID-19 transmission chain in the workplace. Procedures accounting for the following factors can avoid transmission of the disease: 

  • The workers are informed that in case of symptoms of cough or fever, difficulty breathing, sudden loss of smell or taste without nasal congestion or any other symptom associated with COVID-19, they must not report to work; 
  • Identification of workers with COVID-19 symptoms before they enter the workplace, by means such as: 

The information collected in this way is confidential. The employer must take the necessary measures to protect the confidentiality of this information: 

  • When a person exhibits symptoms associated with COVID-19, as indicated on the government website, that person must wear a procedure mask and be isolated in a room;  
  • Once the person exhibiting symptoms has left, prohibit access to the isolation room waiting to clean it and disinfect the surfaces and objects touched by the person; 
  • To find out what isolation instructions apply to your situation, you can consult the self-assessment tool available on the government's website Qué
Physical distancing
  • Whenever possible, a minimum of 1 metre of distancing between people must be maintained at work, from arrival to departure. 
  • Physical distancing or physical barriers are not required while eating. A quality mask must be worn during breaks and at lunchtime when not eating.
  • Handshakes, hugs and other physical contact must be avoided. 
  • Suppliers, subcontractors, partners and clients must be made aware of the measures in place in the enterprise to control the spread of COVID-19 and of the importance of respecting them.

Use of a quality mask in the workplace

  • A quality mask is provided by the employer and worn by workers when physical distancing of 1 metre cannot be maintained or in the absence of a physical barrier.

Adjustments must be made to limit the risk of transmission when the principles of physical distancing cannot be respected: 

  • Use of technological means (telework, hybrid model)
  • Installation of physical barriers (full partitions) between different workstations that are too close to each other or that cannot be spaced (it is recommended that the physical barriers already installed be left in place)
  • Organization of work methods. For example: 
    • prefer teams that are as small and stable as possible 
    • limit outings and trips to those strictly necessary 


  1. Telework is no longer mandatory and a gradual return to hybrid mode is possible according to the terms and conditions determined by the employer.
  2. The following quality masks can be used to protect workers from COVID-19:
    • medical masks meeting ASTM F2100 and EN 14683 Type IIR standards
    • masks certified by the Bureau de normalisation du Québec (BNQ) in attestation document 1922-900 (BNQ website)
    • any respiratory protection device (RPD) equipped with a particle filter, as defined in CSA Standard Z94.4-18, Selection, Use and Care of Respirators, such as N95 or P100 RPDs
Hand hygiene

Frequent hand washing with soap and lukewarm water or with a hydroalcoholic solution with an alcohol concentration of at least 60% for at least 20 seconds limits the risks of transmission in the work environment, especially: 

  • when entering or leaving the workplace
  • before or after touching the face (eyes, nose, mouth); 
  • after coughing, sneezing or wiping the nose; 
  • before and after eating; 
  • after handling something that is frequently touched; 
  • before putting on and removing protective equipment. 
Respiratory etiquette

Respecting respiratory etiquette consists of: 

  • covering your mouth and nose when you cough or sneeze, and using tissues or the crook of your elbow; 
  • using single-use tissues; 
  • immediately discarding used tissues in the trash can; 
  • frequent hand washing; 
  • not touching your mouth or eyes with your gloved or bare hands.


Hygiene measures for tools, equipment and frequently touched surfaces 

Given that the virus responsible for COVID-19 can live on surfaces, application of hygiene measures is necessary: 

  • Ensure efficient operation and maintenance of the ventilation systems, according to the regulatory requirements for the type of facility and the tasks performed; 
  • Clean the sanitary facilities at least every shift and disinfect them daily; (section 165 of the Regulation respecting OHS)
  • Clean the meal areas before each meal and disinfect them daily(section 153 of the Regulation respecting OHS). 
  • Clean the frequently touched surfaces at least every shift and when they are visibly soiled. 
  • Clean shared tools and equipment after every shift; 
  • Use the appropriate cleaning products or disinfectants (see the manufacturer’s recommendations and do not mix cleansers); 

Resources are available online for more information concerning cleaning of surfaces or the recommended disinfectants.   

Transportation of workers

General measures

Mechanical or natural ventilation, as the case may be, should be optimized. Moreover, the vehicle must be ventilated from the outside.

Surfaces touched by workers must be cleaned after each shift. 

In a passenger vehicle or truck

When 2 people or more share the same vehicle, the workers must wear a quality mask at all times. Certain exemptions are provided for the driver (see below).

In a bus

When riding a bus, workers must wear a quality mask at all times. Certain exemptions are provided for the driver (see below).

In an elevator

In an elevator, workers must wear a quality mask at all times.

Conditions for exemption from wearing a mask at all times for drivers 

Drivers may remove their quality mask when they are alone in their vehicle. They must put a mask on as soon as a passenger or co-worker enters. 

When prescription glasses fog up during driving, rigorous prevention measures must be implemented to ensure minimum protection of the driver.

  • Keeping a distance of 1 metre or installing physical barriers
  • Limiting periods where workers are not wearing masks to the strict minimum
