Three pedestrians were sent to hospital with serious injuries within two hours of each other after being struck by vehicles in the city's north end, Toronto paramedics say.

A woman in her 20s, a child, and a man in his 50s have all been transported to hospital with serious injuries following two separate incidents on Tuesday evening.

Paramedics say the pedestrians' injuries are serious, but non-life-threatening.

The first incident happened near the northbound Highway 404 on-ramp at Finch Avenue East, when woman and a child were struck by a car around 8 p.m.

The man was struck less than two hours later near Black Creek and Trethewey drives.

The westbound lane of Finch Avenue East was closed, but has since reopened.
