*Secretariat 1973 1 minute 53 seconds flat. Tank's Prospect 1985 1 min 53 seconds 2/5ths. Louis Quatorze 1996 1 min 53 seconds 2/5ths. Gate Dancer 1984 1 min 53 secons 3/5ths. * Secretariat's time in the 1973 Preakness was flawed when the timer malfunctioned. Using modern technology, it was shown he won in 1:53 flat, and now holds all three Triple Crown records.
Canada became a country on July 1st, 1867 Canada officially became a country on July 1, 1867. The first provinces were Quebec, Ontario, Nova Scotia, and New Brunswick.
Canada formulated as an independent nation state in 1867. Prior to that, it was comprised as a series of colonies of Great Britain. Great Britain abolished slavery in 1833. This took effect in Great Britain and its colonies in 1834, effectively covering the entire British Empire. So there was slavery in what would become Canada prior to 1834, but officially there was never slavery in Canada as an independent nation. I hope this answers the question.
