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 said stations were stocked with ballots based on turnout from the last federal election in 2011.
She said 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, said she was told there were not enough ballots on some remote reserves in the province.
She said some voters were given photocopies of blank ballots instead.
North Wilson said the turnout showed the First Nations vote has mobilized and people want change.
