Two federal polling stations opened late in Ottawa on election day due to volunteers showing up late and ballot boxes being mailed to a wrong address.

In the hotly contested riding of Ottawa West-Nepean, the polling station at Ron Kolbus Lakeside Centre opened about 30 minutes late and Elections Canada staff members were still setting up an hour after polls were supposed to open.

Maciej Andruczyk showed up to vote when polls opened at 9:30 a.m. ET but he wasn't able to vote until 10 a.m., when the polling station eventually opened.

He said he filed a complaint after waiting half-an-hour to vote. He was told it was due to staffing issues at the polling station.

"They said two volunteers didn't show up. However, shouldn't you have somebody in reserve in case the people don't show up? It sounds to me like very shoddy planning, to be honest," Andruczyk said.

"They were apologetic and they tried to explain but that doesn't change the facts, and the facts are that, potentially, a few dozen people were deprived of the right to vote."

He said he saw about 30 voters walk away, and he hopes the polling station will be allowed to remain open until 10 p.m. to make up for the half-hour of voting time lost Monday morning.

Orléans polling station opens 1 hour late

In the Orléans riding the polling station at St. Francis of Assisi School opened an hour late.

Its ballot boxes were delivered to a wrong address due to an administrative error, according to Elections Canada spokesman James Hale.

The ballot boxes had to be sent back to Elections Canada before being delivered to the school for security reasons, said Hale.
