Exhibit 99.1

Notice of 2022 Annual Meeting and

Notice of availability of meeting materials (Registered)

Throughout this notice, Enbridge and our means Enbridge Inc. and you, your, and shareholder mean a beneficial holder of common shares of Enbridge.

You are receiving this notice because Enbridge is using the notice and access system to deliver to you our Management Information Circular and other proxy-related materials, including our 2021 Annual Report, for our Annual Meeting of Shareholders by providing you with electronic access to the documents instead of mailing paper copies. Notice-and-access is an environmentally-friendly and cost-effective way to distribute the materials because it reduces printing, paper and postage. Enclosed with this notice is a form of proxy so you can vote your shares.
