You are receiving this notification as OpSens Inc. (the "Corporation") is using the notice and access mechanism (the "Notice and Access Provisions") to deliver the meeting materials to its registered and beneficial shareholders (the "Shareholders") for its annual general and special meeting of Shareholders to be held on Tuesday, January 18, 2022 (the "Meeting") and to advise that the proxy materials for the Meeting are available on the Internet. The Notice and Access Provisions are a set of rules that allow reporting issuers to post electronic versions of proxy-related materials via the System for Electronic Document Analysis and Retrieval and the Internet, rather than mailing paper copies of such materials to Shareholders. The Corporation will not use the procedure known as "stratification" in relation to the use of Notice and Access Provisions. Stratification occurs when a reporting issuer using the Notice and Access Provisions provides a paper copy of a management proxy circular to certain shareholders with the notice package.

This communication presents only an overview of the more complete proxy materials that are available to you on the Internet. We remind you to access and review all of the important information contained in the management proxy circular dated December 8, 2021 (the "Circular") and other proxy-relatedmaterials before voting.

The Circular and other relevant materials are available at:
