Canada spans Atlantic to Pacific. Toronto's sunrise is not Vancouver's, and both diverge from IST by 9.5–13.5 hours depending on the season. City pages here use America/Toronto for the Greater Toronto Area and Peel Region, America/Vancouver for the Lower Mainland and America/Edmonton for Alberta, so tithi-at-sunrise for Ekadashi is the local civil morning.
Ontario, British Columbia and Alberta observe DST on the US schedule (March–November). Saskatchewan stays on CST year-round and is not in this tranche. Confirm the zone on the city page rather than converting from Eastern by hand.
