About the project
TRL is undergoing renovations that will replace the majority of the building's exterior windows. This renovation will address the deteriorating window conditions to protect users and collections, as well as maintain building standards as part of the State of Good Repair (SOGR).
Why are we doing this renovation work at TRL?
The majority of windows from the building's original construction in 1977 are starting to fail. This project will replace these windows and frames with new ones that can better control heat from the sun, and ultimately, better control the temperature during all seasons. The windows are made using required Toronto Green Standard bird friendly fritted glass to help prevent birds from flying into the glass.
How long will the construction last?
The total windows replacement construction period is estimated at 18 to 24 months and will be completed in five phases. Phase one north-east window replacement was completed and spaces reopened to the public in April 2026. Phase two replacements of the pyramid or punch windows will be completed in July 2026. Phase three replacement of sloped and vertical windows at the south-west side of the building started in March 2026 and will be completed November 2026. Phase four replacement of ground floor windows in select areas will start in May 2026 and completed in July 2026. The fifth and final phase replacement of clerestory windows (skylights) is set to start in Q3 2026. We will communicate details for the subsequent phases on this page as they are confirmed.
Which service areas/floors in TRL will be affected?
The windows work is being completed in phases to ensure as little disruption to public spaces and services as possible.
During phase two, the area directly adjacent to pyramid windows will be closed while work is underway. Access to collections in some areas will also be impacted.
During phase three, all public areas near the windows on the south-west side of the building on floors 3 to 5 will be affected. The final phase in the public area will address replacement of the clerestory windows (skylights) after completion of phase three.
What is changing now?
- Some collections, public computers, and ScanPro microfilm scanners will be moved
- Study tables will be reduced
- Computers on the 5th floor will not be available
Can I still book a study space or use a computer?
Yes, you can still book study rooms and pods, but there may be fewer available on each floor. Staff can help you with booking if you have any questions at the branch.
While there are no computers available for public use on the 5th floor, there are public computers available for use on all other floors. Ask staff for assistance locating or booking these computers.
What will happen to the event I booked at TRL through Venue Rentals?
The phased approach to the window replacement work at TRL includes the continued operation of the Premium Venue Service. Please reach out to the Venue Rentals team at venuerentals@tpl.ca with any questions about your booking.
What will the renovation look like inside and outside of TRL?
A temporary barrier and fencing will protect the interior and exterior construction areas. Exterior scaffolding will be installed on the outside of the building, once the interior temporary barrier is installed.
There may be dust outside associated with this renovation at times, as well as temporary pedestrian traffic and walkway modifications.
Work at times may be noisy. Please speak with staff to help identify quieter locations in the building. Please note that work may shift from day to day, and staff may not know which areas will be worked on or when the work will be completed for the day.
