The Royal Ontario Museum is holding a ceremonial groundbreaking today to kick off a $200 million renovation and expansion, and sources say that the ROM may have locked up one of the major gifts it needs to fund the project. “Insiders are abuzz with unconfirmed reports that [Canadian philanthropist Galen] Weston is about to hand over $25 million — which could put the ROM close to its phase one campaign goal of $150 million, and position the museum fundraising blitz to move into phase two, with a goal of an additional $50 million for a total of $200 million.”
