<P> Thousands of drum players , dancers , vendors and visitors come together every Sunday afternoon throughout the temperate months , occupying much of the open space on the eastern edge of Mount Royal Park ( also known as Fletcher 's Field ) . Jeanne - Mance Park , located directly across Avenue du Parc from where the Tam - Tams take place , serves as the city 's main outdoor sporting ground . As such , the entire area is generally quite popular on Sundays in the summertime , drawing an exceptionally diverse crowd to myriad activities . The Tam - Tams typically start around 10 : 30am and continue until sunset . It is not an officially sanctioned nor sponsored event , simply a regular if technically spontaneous event . As such , it 's difficult to pinpoint when it started or what motivated the first drum circle . </P>
