As of 2017[update], Intact was the largest provider of property and casualty insurance in Canada by annual premiums.

In the 1980s, the company continued to grow with the acquisition of three well-known regional insurers - Commerce Group and Belair in Quebec, and Western Union in Alberta.

That was soon followed with an initial public offering and the start of trading on the Toronto Stock Exchange with ING Group retaining 70% ownership.

The company came together through a series of major acquisitions starting in 2011 when Intact acquired Axa Canada for $2.6 billion.

In 2014, Intact acquired Metro General Insurance Corporation which operated largely in Newfoundland and Labrador.
