The Toronto Transit Commission (TTC) has made several adaptations to its services in response to the COVID-19 crisis. Here are some key measures they have implemented:

1. Enhanced Cleaning and Disinfection: The TTC has increased cleaning protocols, focusing on surfaces frequently touched by passengers, such as handrails, handles, and seats. They have introduced hospital-grade disinfectants to ensure higher sanitation standards.

2. Mandatory Mask Policy: Passengers and staff are required to wear masks or face coverings while on TTC properties and vehicles. This policy aims to reduce the spread of the virus, especially in enclosed spaces.

3. Capacity Limits: The TTC has introduced capacity limits on buses, streetcars, and subway trains to promote physical distancing. They have marked certain seats as unavailable to encourage passengers to maintain space between one another.

4. Service Adjustments: In response to fluctuating passenger demand, the TTC has adjusted service levels on various routes, adding more vehicles during peak times and reducing service when necessary. This flexibility helps manage crowding and maintain safety.

5. Contactless Payment Options: The TTC has encouraged the use of contactless payment methods, such as PRESTO cards, to limit physical interactions between passengers and TTC personnel.

6. Protective Shields for Operators: Barriers have been installed on vehicles to protect operators, helping to minimize their contact with passengers.

7. Communication and Signage: The TTC has increased communication efforts, using signage and announcements to remind passengers of public health guidelines and to provide updates on service changes.

These efforts highlight the TTC's commitment to public safety during the pandemic. For more detailed and current information, you can visit the official TTC website at TTC COVID-19 Updates.
