Although a work holiday is given to employees of the federal and many municipal governments, the Government of Ontario has not defined this day as a statutory holiday and it is mentioned in neither Ontario's Employment Standards Act nor Retail Business Holidays Act. Schools are generally already closed, regardless of the holiday's status, because of summer vacation. The Caribbean Cultural Festival, formerly known as Caribana, is held this holiday weekend in Toronto, coinciding with Emancipation Day.

At approximately 05:15 ChST on 26 March (19:15 UTC on 25 March), the descent began. At 07:52 ChST (21:52 UTC), Deepsea Challenger arrived at the bottom. The descent lasted 2 hours and 36 minutes and the recorded depth was 10,898.4 metres (35,756 ft) when Deepsea Challenger touched down. Cameron had planned to spend about six hours near the ocean floor exploring but decided to start the ascent to the surface after only 2 hours and 34 minutes. The time on the bottom was shortened because a hydraulic fluid leak in the lines controlling the manipulator arm obscured the visibility out the only viewing port. It also caused the loss of the submersible's starboard thrusters. At around 12:00 ChST (02:00 UTC on 26 March), the Deepsea Challenger website says the sub resurfaced after a 90-minute ascent, although Paul Allen's tweets indicate the ascent took only about 67 minutes. During a post-dive press conference Cameron said: ``I landed on a very soft, almost gelatinous flat plain. Once I got my bearings, I drove across it for quite a distance ... and finally worked my way up the slope.'' The whole time, Cameron said, he didn't see any fish, or any living creatures more than an inch (2.54 cm) long: ``The only free swimmers I saw were small amphipods''--shrimplike bottom-feeders.
 Question: has anyone been to the bottom of challenger deep Context: O'Malley moves in with new intern Lexie Grey (Chyler Leigh), Meredith's half-sister. Lexie and O'Malley discover that he only failed his exam by a single point, leading him to confront Richard Webber (James Pickens, Jr.), the chief of surgery, to ask for a chance to retake the exam. He passes the second attempt, and begins to distance himself from Lexie, who has fallen in love with him. O'Malley supports Stevens when she discovers she has melanoma, and walks her down the aisle as she marries Karev. O'Malley begins to display a talent for trauma surgery, and is told by the chief of trauma surgery Owen Hunt (Kevin McKidd) that it is definitely his specialty. He then abruptly and inexplicably decides to join the U.S. Army. While his friends at the hospital prepare an intervention to convince O'Malley to stay, they all work on a severely disfigured John Doe, brought in after a horrible bus accident, in which he pushed a woman out of the way and saved her life. O'Malley writes on Meredith's hand ``007'' and she realizes it is her friend George. She runs to tell the other surgeons and they rush him to surgery. However, he flatlines and is ultimately declared braindead. There is confusion on if John Doe is really George and Callie confirms by a freckle on his hand. His organs are donated after Stevens confirms that is what O'Malley would have wanted, and he is buried a week later.
