File a Technical Dossier

You must obtain a permit from TSSA for any regulated amusement device being operated in a public venue.

Technical Dossier Filing Overview

The Technical Standards and Safety Authority (TSSA) reviews and files new or altered amusement device designs.

Before a new or altered Amusement device can be filed, its design is subject to an engineering review to ensure compliance with Ontario safety standards as specified in, 

Technical Dossier applications for Amusement devices as defined in the regulation must be submitted by a Professional Engineer (PEng) on behalf of an amusement device owner.

Technical Dossier - For New or Altered Devices (O.Reg 221/01 s. 9)

Follow these steps to prepare a Technical Dossier package for filing by TSSA Engineering.

  • Complete the Application form, transmittal form and the appropriate Specification Sheets from the file below.

Piggyback Submissions 

If the amusement device is identical in all aspects to a device that has been already filed with TSSA under the current applicable codes, it may be possible to file a new technical dossier as a piggyback on another, provided the device meets or exceeds the requirements of the code referred to in Ontario Regulation 221/01 – Amusement Devices, Section 9 (3), Section 9 (3). 

To file a piggyback submission, you need to know another licensed amusement device operator who has the same ride as you and is willing to share their dossier with you. TSSA does not provide lists of owners and their filed devices. 

Structurally unique devices such as zip lines, go-kart tracks, or waterslides generally cannot be filed as piggybacks.


Additional Files for Altered Devices

In addition, the above specification sheets for altered designs (alterations to a device), the following form may be required for alteration submissions

A variance from regulations and adopted safety standards may be reviewed for consideration, but it is not guaranteed to be granted,

Variances allow designers flexibility to use designs that do not strictly comply with current regulations but include other methods to ensure equivalent amusement device safety.

Service fees to evaluate variances are charged at an hourly rate.
