Voter turnout was so high on some reserves on the Prairies that there were reports of a handful of polling stations running out of ballots.
Leanne Nyirfa with Elections Canada says stations were stocked with ballots based on turnout from the last federal election in 2011.
She says a station on Siksika Nation, east of Calgary, went without ballots for about 15 minutes until workers could deliver more.
Sheila North Wilson, grand chief of a group representing First Nations in northern Manitoba, says she was told there were not enough ballots on some remote reserves in the province.
She says some voters were given photocopies of blank ballots instead.
North Wilson says the turnout showed the First Nations vote has mobilized and people want change.
