An annual survey of Group Risk advisers has placed Canada Life Group Insurance division at the top of the industry for the third year in a row.
In addition, the survey, conducted by independent research organisation ORC International, put Canada Life top for service for the sixth consecutive year.
The insurer noted that in 2013 medical underwriting was identified as an opportunity for improvement, and it now claims first place.
The ORC International survey has tracked service and proposition across all leading Group Risk providers for seven years. 172 advisers responded to the survey in 2014; 79% had done business with Canada Life in the prior 6 months, up from 74% the year before.
Ian McMullan, Managing Director at Canada Life Group Insurance, said: "We were delighted to be number one in the Swiss Re Group Watch 2014 survey with the largest market share by companies covered, by employees covered, and for the first time by premium.
"Specifically, retaining number one for service is becoming a tradition and we will continue to develop our support for advisers, employers and employees without complacency.
"An exciting set of other results, such as reaching number one for medical underwriting shows the hard work that we have put into areas where we were not first in 2013."
