Suncor Energy Inc. — Suncor Energy Inc.now has strong first-quarter earnings in its arsenal and a publicized plan to improve worker safety, but some observers say that won't be enough for the Calgary-based oil giant to fend off an aggressive activist investor.

Little touted Suncor's profits of $2.95 billion in the first quarter — up from $821 million in the same period of 2021 — as well as the highest quarterly cash flow in the company's history as proof.

RioCan Real Estate Investment Trust (TSX:REI.UN). Down 84 cents, or 3.85 per cent, to $20.99.
