Marivic Lezada, 31, was in the backseat of the family van as her husband Jonald drove along Highway 174 near Blair Road just after 5 a.m. when she realized she wasn't going to make it to the hospital.

"I was just telling him, 'Quick, quick, quick, I can feel the head already,'" said Lezada.

After her water broke earlier in the morning, the Orleans couple had packed up their 18-month-old son and soon-to-be four-year-old daughter to dash to the hospital.

But Lezada, feeling more and more powerful contractions along the way, instead told her husband to call 911 and get off the highway.

They pulled off the highway onto St. Laurent Boulevard and into the driveway of his sister's home, where Jonald Lezada said a paramedic dispatcher coached him through the delivery.

He caught his new daughter in a towel, and when she did not immediately cry, he turned her face down and patted her back as the dispatcher instructed. That's when the baby began to cry.

"That was a very good thing when I heard that," he said.

Paramedics arrived shortly after and took the family to the hospital.

Marivic Lezada said it was a good catch.

"He's a doctor now, I'm calling him doctor," she laughed.

Both Veena Gliceria Lezada — weighing seven pounds, nine ounces — and her mother were in stable condition when they arrived at hospital, said paramedics. They are expected to stay overnight at the hospital.

Ottawa paramedics say they have to give birthing instructions over the phone as many as 20 times a year.
