The Katz Group of Companies is a Canadian privately-owned enterprise, with operations in sports and entertainment and real estate development.

Katz Group’s former pharmacy business and health-related companies operated under the banner "Rexall Health".

[4] Katz obtained financing from Vencap Equities, a venture capital fund established by the Alberta government to support local entrepreneurs.

[3] On January 30, 2012, Katz agreed to sell its Drug Trading Company Ltd. to McKesson Corporation for roughly $920 million in cash.

[5] Drug Trading Company is a marketing and purchasing arm for a network of over 850 independent pharmacies that primarily operate under the I.D.A.

[3] Additionally on January 30, 2012, Katz acquired the 18-store Dell Pharmacies chain that operates in the Hamilton, Ontario, area.

[6] Regarding the deal, National Bank Financial analyst Vishal Shreedhar suggested, "... Katz Group wants to exit the small pharmacy-focused independent/franchise business because it is most impacted by recent drug reforms.

"[7] Katz Group continues to supply Rexall products to the independent and franchise pharmacies sold to McKesson.

On March 2, 2016, Rexall announced that it was being sold, in entirety, by Katz Group to the McKesson Corporation, a San Francisco-based pharmaceutical company.

The city’s portion of arena funding will be paid through a Community Revitalization Levy and will not result in any new cost to taxpayers.

[19] With Rogers Place at its core, Katz Group has begun construction of the Edmonton Arena District (EAD), which quickly became Canada’s largest mixed-use sports and entertainment development.

The EAD covers 25 contiguous acres of downtown Edmonton and features a 50,000-square-foot public plaza, two office towers, a JW Marriott hotel, a Gateway Casinos gaming and entertainment facility, a Cineplex movie theatre complex, over 1,000 luxury condos and rental apartments, and 270,000 square feet of retail space at a total cost around $2.5 billion.
