Saint Patrick's Day (MONTREAL) One of the longest-running Saint Patrick's Day parades in North America occurs each year in Montreal, whose city flag includes a shamrock in its lower-right quadrant. The parades have been held continually since 1824. In Manitoba, the Irish Association of Manitoba runs an annual three-day festival of music and culture based around St. Patrick's Day. In 2004, the CelticFest Vancouver Society organised an annual festival in downtown Vancouver to celebrate the Celtic Nations and their culture. This event, which includes a parade, occurs the weekend closest to Saint Patrick's Day. In Quebec City, there was a parade from 1837 to 1926. The Quebec City St-Patrick Parade returned in 2010 after an absence of more than 84 years. For the occasion, a portion of the New York Police Department Pipes and Drums were present as special guests. The Toronto Maple Leafs hockey team was known as the Toronto St. Patricks from 1919 to 1927, and wore green jerseys. In 1999, when the Maple Leafs played on Saint Patrick's Day, they wore green St. Pat's retro uniforms. There is a large parade in the city's downtown core on the Sunday prior to 17 March which attracts over 100,000 spectators. Some groups, notably Guinness, have lobbied to make Saint Patrick's Day a national holiday. Currently, Newfoundland and Labrador is the only jurisdiction where Saint Patrick's Day is a provincial holiday. In March 2009, the Calgary Tower changed its top exterior lights to new green CFL bulbs just in time for Saint Patrick's Day. Part of an environmental non-profit organisation's campaign (Project Porchlight), the green represented environmental concerns. Approximately 210 lights were changed in time for Saint Patrick's Day, and resembled a Leprechaun's hat. After a week, white CFLs took their place. The change was estimated to save the Calgary Tower some $12,000 and reduce greenhouse gas emissions by 104 tonnes. St. Patrick's day occasionally turns violent due to the large number of intoxicated individuals celebrating in Canada. This was seen, for example, in the London, Ontario area in 2012, where college students lit a TV van on fire then threw bottles at firefighters (attempting to put out the fire) and police officers in the area.
