Canadian parks police say they rescued five people from the Niagara Gorge during two incidents over the weekend.

On Saturday evening, two Toronto-area visitors called 911 after they became stranded in the dark while hiking the rugged Niagara Glen overlooking the whirlpool downstream from Niagara Falls.

The Niagara Parks Police say members of the department's High Angle River Team escorted the pair out at about 9:45 p.m.

The High Angle River Team was called again Sunday night, after three men climbed over a retaining wall downstream of the falls and into the gorge. The team brought one man out while firefighters used an aerial ladder to free another. The third man climbed out on his own. All face trespassing charges.

Police didn't release any identities.
