"It's none of their business what we do in the city of Edmonton," he said. "I don't butt into Toronto's business. I don't appreciate it at all."
Mandel said it's "disrespectful" for another city to pass a resolution about what Edmonton should or shouldn't do.
Toronto city council voted Tuesday to move the Toronto Zoo's three remaining elephants to the Performing Welfare Society in California before the end of the year.
The motion also called on the City of Edmonton to "invite independent veterinarians to assist in assessing Lucy's condition and treat her, if necessary, so that she can be sent to one of the two elephant sanctuaries in the United States as soon as possible."
The city has long maintained a move would be too dangerous for the 37-year-old Asian elephant. The city's veterinarian said a breathing problem could kill her if she becomes stressed.
Mandel went on to praise city staff for the care they're giving the elephant.
Mandel said he wasn't offended by Paul McCartney allowing an animal interest group to petition concert goers at his Wednesay and Thursday night shows.McCartney gave permission to Voice for Animals to get signatures on a petition calling for a panel of veterinary experts to examine Lucy.
In 2010, the Alberta Court of Queen's Bench dismissed an action to move the elephant by People for the Ethical Treatment of Animals and Zoocheck.
