Canadian Reuters Heiress Pays Westside Record $48.7 Million for Shane Smith’s Santa Monica Estate

But with a reported net worth of $7.5 billion, Thomson can afford to indulge her every real estate whim. Canada’s second-richest woman, she’s a member of the ultra-private Thomson clan, which has for decades reigned supreme as Canada’s wealthiest family. Forbes says the Thomsons have a collective net worth of about $44 billion, as stewards of a media empire founded by Taylor’s grandfather Roy Thomson. Their biggest asset: Woodbridge, the holding company that owns a controlling stake in Thomson Reuters; Taylor herself reportedly retains a 14% stake in Woodbridge.
