从他们的网站摘录一句：

North America's Largest Street Festival
June 15th - August 15th, 2010*        * Subject to change. 

从6月15日到8月15日，wow，持续两个月啊。

不过，也不要太遗憾，感觉是刚刚开始，只是精彩的活动免费的很少，再摘录一段，关于游行的，这个一定要去看：

Among the highlights is the Parade, one of the largest in North America. Thousands of brilliantly costumed masqueraders and dozens of trucks carrying live soca, calypso, steel pan, reggae and salsa artists jam the 1.5 km parade route all day, to the delight of hundreds of thousands of onlookers.

这是游行的时间安排，座位票收费，站票免费：

Scotiabank Caribana Parade
Place: Exhibition Place & Lake Shore Blvd
Date: July 31st
Time: 10:00 am - 6:00 pm
Cost: Free/$20.00

即7月31日中午10点到下午6点，在Exhibition Place和Lake Shore Blovd。

Tickets can be purchased for the seated area inside Exhibition Grounds. This showcase event features an incredible display of colour and pageantry, commencing at Exhibition Place and proceeding west along Lake Shore Boulevard. Exhibition Place and Lake Shore Boulevard will come alive with the sights and sounds of Carnival!

介绍它的历史的：

Caribana was created in 1967 as a community heritage project for Canada's Centennial year. Based on Trinidad Carnival, the Festival now also includes the music, dance, food and costumes of Jamaica, Guyana, the Bahamas, Brazil and other cultures represented in Toronto - the world's most culturally diverse city.

卡里巴纳作为加拿大一百周年的社区遗产项目创建于1967年。它基于特立尼达狂欢节，现在这个艺术节还包括牙买加、圭亚那、巴哈马、巴西和多伦多--世界上最多元文化的城市--的其他文化的音乐、舞蹈、食品和服饰。

这个网站很详细，图片很多，它说是7月15日开始，8月13日结束：
