An Air Canada flight from Edmonton to Toronto on Sunday morning landed safely after the pilot declared a mayday.

The aircraft was on its final approach to Toronto's Pearson airport when the pilot told air traffic control that he had to abandon the planned landing because of "flight control" issues. 

Police were alerted at 6:30 a.m. ET., and set up a staging area with officers and ambulance on standby, according to Const. Fiona Thivierge with Peel Regional Police.

The plane circled over Lake Ontario until it was determined that it was safe to land.  

"They landed without incident, fortunately,” Thivierge said.

None of the 93 people on board were injured, the airline and police said. The aircraft was carrying 87 passengers, two pilots and four flight attendants, Air Canada said.

A flight control indication light came on upon arrival in Toronto, the airline said.

"Our crew are well trained to handle these events and followed procedures by declaring an emergency," Air Canada spokesperson Isabelle Arthur said in an email statement to CBC News.

"We are currently taking care of our customers and maintenance is inspecting the aircraft."

Flight AC1174 left Edmonton at 1:10 a.m. MT and arrived in Toronto at 7 a.m. ET.

Passengers took to social media to share their scary experiences.

"The captain and crew of @AirCanada flight AC 1174 from Edmonton to Toronto were amazing... Calm cool and collected. Thank you to all," Twitter user Monique Auffrey said.

"I actually thought I might die today. I said a few prayers. #grateful Thanking God and the amazing @AirCanada crew," Auffrey continued.

"Thanks to the amazing crew of flight AC1174 @AirCanada and ground crew My 1st and hopefully my only emergency landing. Still a little shaky," Twitter user Debbie Williams said.
