Data Access for Trainees

The CLSA provides alphanumeric data to qualified graduate students and postdoctoral and clinical fellows at no cost. Providing free access to CLSA data for trainees has two objectives:

  • To build capacity for population-based research in Canada
  • To introduce trainees to the CLSA platform, increasing awareness of the data holdings, and providing a foundation for emerging research careers

Who Can Apply

The CLSA data are available to approved Canadian and international researchers and trainees. Fee waivers are available for trainees enrolled at a recognized Canadian institution and for Canadian trainees based at institutions outside Canada who are funded through a Canadian funding agency.

A fee waiver (some restrictions apply) will be granted to trainees if the CLSA dataset requested will be for the sole use of the graduate student’s thesis research or the postdoctoral or clinical fellow’s research project (limit one waiver per fellow).

Data Availability

Approved trainees can access alphanumeric data within the CLSA research platform, including questionnaire and physical assessment data, biomarkers, genomics, epigenetics, metabolomics, linked data and COVID-19 data. Additional fees apply for imaging and raw data.

How to apply

For trainee applications, the primary applicant must be the supervisor, on behalf of the trainee. The supervisor is responsible for the content and final submission of the application and closely works with the trainee to prepare the application. As primary applicant, the supervisor must also request a Magnolia user account on behalf of the trainee to allow the trainee access to the application.

For applications to be considered for a fee waiver, the trainee must initiate the project application in Magnolia. If the supervisor initiates the application, the trainee cannot be added.

Frequently Asked Questions

Graduate students (Masters or PhD) who wish to obtain the CLSA data for the sole purpose of their thesis, and postdoctoral or clinical fellows (limit 1 waiver per fellowship) who wish to obtain the CLSA data for the sole purpose of their postdoctoral or clinical fellowship project, who are enrolled at Canadian institutions for their graduate degree, postdoc, or clinical fellowship, can apply for a fee waiver. This fee waiver only applies to alphanumeric data. Any additional data requested, such as images and raw data, have associated fees. The trainee fee waiver cannot be applied to CIHR catalyst grant applications. Canadian trainees working outside Canada but funded through a Canadian source are also eligible for a fee waiver. The request for a fee waiver must be checked in Part 1 of the CLSA Data and Biospecimen Access Request Application in Magnolia.

Once you submit your CLSA Data and Biospecimen Request Application, you can track the progress of your application through Magnolia, the online application system. Once you have begun the application process, it is your responsibility to check your email (including your folders for junk, spam, etc.) for notifications from Magnolia. You may be contacted by the Data Access Team, if additional information is required. You will be notified about the approval status of your application approximately three months after the submission deadline. If your application is approved, a CLSA Access Agreement must be negotiated and signed between McMaster University and your institution. This part of the process can take a variable length of time (up to an additional three (3) months) and is not under the control of the CLSA. You will also need to provide evidence of ethics approval for your project, if you had not done so within your initial application. Please be aware that these steps may affect the length of time that it takes for the data to be released to you. Once all parties have signed the CLSA Access Agreement and proof of ethics approval has been received by the CLSA, your data will be released within 10 working days. Please note that the release of additional data (images and raw data) will require more time (one to three months, depending on the request). When planning for your project, you must include in your timeframe at least six (6) months from the application submission deadline to the time you receive your dataset.

Yes. Please note that ethics approval is not required at the time of the application to use CLSA data, but no data or biospecimens will be released until proof of ethics approval has been received by the CLSA. Should your institution not require a full ethical review for the use of de-identified data, please provide a letter from your Institutional Review Board to this effect. Ethics approval must be obtained only from the primary applicant’s institution, not from all of the institutions of the members of the project team.

The CLSA DataPreview Portal has been designed to help researchers browse available variables in the CLSA dataset and find basic frequencies. Should you need additional information not available through the DataPreview Portal to determine the feasibility of your proposal, please contact us at access@clsa-elcv.ca. We can provide simple cross-tabulations (of two or three variables) from cross-sectional data. While we do our utmost to respond to data queries to help potential users ensure that their proposal is feasible, please note that we are not resourced to provide statistics on change across time-points or more in-depth statistical support.

Graduate students (Masters or PhD) enrolled at Canadian universities who wish to obtain the CLSA data for the sole purpose of their thesis, and postdoctoral or clinical fellows (limit 1 waiver per fellow) who wish to obtain the CLSA data for the sole purpose of their postdoctoral project, may request a fee waiver.

Fee waivers apply to the CLSA portion of the data access fee only.

The CIHR Catalyst Grants for the use of CLSA Data are not eligible for Fee Waivers for the CLSA portion of the data access fee.

The goal of the CLSA is to enable data access as widely as possible, however, an application for data access can be denied. There may be some instances when an applicant is asked to revise and resubmit an application at the recommendation of the Data and Sample Access Committee (DSAC). To avoid applications being sent to the DSAC that are not appropriate, we try to work with interested researchers before the application is submitted, to provide them with information about the available data and feasibility of a project. During the application process itself, we ask applicants to correct errors and omissions and provide feedback from the DSAC review, so that applicants can clarify or revise and resubmit a proposal. Failure to provide the level of detail sufficient to assess the study feasibility could lead to the application being not approved.

SPOTLIGHT ON CLSA TRAINEES

Graduate students and postdoctoral fellows utilize CLSA data to investigate health and aging across scientific disciplines, fostering training in longitudinal data analysis and paving the way for careers in population health research. Hundreds of trainees contribute to the CLSA at every stage, from data collection, curation through to data analysis. The trainee profiles below offer deeper insights into their research, connections with CLSA, and future career paths.

“Working with the CLSA has provided me with valuable opportunities to enhance my research skills, analyze complex longitudinal data, and collaborate with interdisciplinary teams. Engaging with diverse populations and addressing health disparities aligns with my commitment to equity, preparing me for future success in academia and beyond.”
