Doug Loates had complained to the company after his daughter and her husband in Edmonton found the words "You Retard" under the cap of a bottle of Vitaminwater.
Loates was initially unhappy with the company's first attempt at an apology but says the second attempt from David Thomson, a vice-president with Coca-Cola Refreshments Canada, was more personal and he accepts it.
The company has cancelled the promotion that paired randomly generated English and French words on the lids of bottled water.
Loates found the message on the cap particularly offensive because he has a daughter who is developmentally delayed.
A company spokesperson has explained that the problem was the word lists for each language were approved separately and that in French, "retard" simply means late.
