Marine transportation occurrence data from January 1995

With a view to advancing transportation safety, the TSB is publishing data from its Marine Safety Information System (MARSIS) on reportable accidents and incidents (together called occurrences) for use by industry and the public. The TSB gathers these data in the course of its investigations and uses them to analyze safety deficiencies and identify risks in the Canadian transportation system.

Accidents and incidents are reported in accordance with the TSB Regulations that were in effect at the time of the occurrence.

The dataset is composed of 6 tables in CSV format.

Content of the dataset

Some data collected by the TSB and recorded in MARSIS will be excluded from the public database to protect third party, personal and privileged information, in accordance with the Canadian Transportation Accident Investigation and Safety Board Act, the Privacy Act and the Access to Information Act.

The data in text fields are provided in English and in French, while free-text fields contain data in the language in which they were entered. Some of the data in the datasets is from sources not subject to the Official Languages Act and are therefore available only in the language in which they were provided.

Data dictionary

The data are described in the data dictionary for this dataset, which is available in CSV [79 kb].

Release schedule

The MARSIS dataset is released on or soon after the 15th of each month, and contains data from January 1995 to the last day of the month preceding its release.


The dataset is for information purposes only. The user of the dataset assumes all responsibilities for its use and for verifying its completeness and accuracy for both critical and non-critical uses and applications.

The data in MARSIS have been collected by the TSB from third-party sources believed to be reliable. As many occurrences are not formally investigated by the TSB (see the Occurrence Classification Policy), information pertaining to some occurrences may not have been validated. Consequently, the data are provided on an as-is basis, and the TSB does not warrant their quality, accuracy, reliability, or completeness.

In no event will the TSB be liable for any direct, special, indirect, consequential or other damages, however caused, arising out of or in connection with the use of any data contained in this dataset. If you find any errors, please report them to
