The abductions add to a string of kidnappings of foreigners in the south since the early 1990s, most often by Islamic militants seeking to extort ransoms, although the latest culprits were not immediately identified.
Police said armed men sailed two motorboats into a marina on Samal island just before midnight on Monday and seized the four from aboard yachts, apparently knowing exactly who they wanted to abduct, police said.
"They appeared to target the foreigners. They went straight for the yachts," Superintendent Antonio Rivera, a local police spokesman, told AFP.
Law enforcement boats and helicopters were scouring the waters around the island on Tuesday to try to stop the kidnappers from leaving the area, according to Rivera, but they appeared to have escaped.
"We still don't have anything. We're blank. No group has taken responsibility and there is no demand for ransom."
A police report identified the Canadian tourists as John Ridsdel, 68, and Robert Hall, 50. The Norwegian, who was working at the marina, was identified as Kjartan Sekkinstad, 56.
The Canadian and Norwegian embassies in Manila declined to comment.
A Norwegian foreign ministry spokeswoman in Oslo, Lothe Salvesen, confirmed to AFP that one of its citizens had been abducted in the Philippines, but gave no further details.
President Benigno Aquino, who was at the resort last week for a meeting with political allies, was monitoring developments and authorities were doing their best to find the captives, his spokesman told reporters.
"The investigation is in full swing, simultaneous with pursuit operations," spokesman Herminio Coloma said.
The area, about 800 kilometres (500 miles) southeast of Manila, is a popular stop for foreign tourists who sail around the nation's many tropical islands.
But the Philippines' southern region has endured decades of conflict, with Muslim rebels waging a separatist conflict that has claimed tens of thousands of lives.
Parts of Mindanao are also home to more extreme Muslim militants, the most infamous of which is the Abu Sayyaf.
