Ramdat Punwassie told the Canadian Broadcasting Corp. he called authorities after discovering the snake about 10 p.m. Tuesday.
"I didn't want to take chances," the native of Guyana said Wednesday. "I close the door and call for help. I see [snakes] in my country. This is the first time I see it here."
Two Toronto police officers removed the python, which had slithered into Punwassie's bathtub, and turned it over to the city's animal services department.
It was the officers' second snake call of the day. Hours earlier, they had removed a 3-foot corn snake that had crawled out of a wall in an apartment in another building in the neighborhood.
Neither snake is venomous. They will be turned over to a reptile zoo if the owners can't be located, police said.
"Like finding a stray dog, now we're finding stray snakes," Staff Sgt. Leslie Hildred said.
