The 34-year-old equalled her own championship record with a second time clearance at 1.91 metres  at Toronto's Varsity Stadium, having won at the Central American and Caribbean Games in Colombia last week as well.

"I am excited to win the title again," she said.

"It's always my goal.

"I am really in good shape.

"I was hoping to jump higher.

"My first attempt at 1.94m was really close, but I am thankful I was able to come out with the win so I am pleased with that.

"I now have a wildcard for the Pan American Games and the [2019] World Championships."

The jumper, who also won at the Commonwealth Games in Australia in April, will next compete at the International Association of Athletics Federations Diamond League final in Zurich.

In all, eight records were set at the Varsity Stadium today.

The North American record-holder in the hammer throw, Deanna Price from the United States, improved her previous record with a throw of 74.60m.

Eldred Henry from the British Virgin Islands then threw a new national record of 20.63m in the men's shot put to finish fifth, before Cuba’s Yalme Perez threw a new championship record in the women's discus, with a mark of 61.97m.

Three US athletes then set records in the distance events.

Mel Lawrence finished the 3,000m steeplechase in 9mins 45.36secs, before Rachel Schneider managed 15:26.19 in the 5,000m and Lopez Lomong clocked 29:49.03 in the 10,000m.

The championship record was then beaten twice in the semi-finals of the womn’s 100m hurdles, setting us up for an exciting final.

Jamaica’s 2015 world champion Danielle Williams set the tone with a record of 12.72 in the first heat, but it did not last long at all as the US’ world record-holder and world indoor champion Kendra Harrison then lowered it to 12.66 in the second semi-final.

Fifteen finals in all will be contested tomorrow, including the 100m, 400m, 800m and the sprint hurdles for both men and women.
