The City Clerk's office has sent Mayor Rob Ford a letter clarifying Municipal Elections Act rules after he was spotted at mutliple advance polling stations in the last week, City of Toronto spokesperson Jackie DeSouza confirms.

According to DeSouza, an election official asked Rob Ford to leave the polling station at J.J. Piccininni Community Centre in Ward 17 on Saturday after arriving there with an elderly voter. Ford had driven the resident to the polling station and shortly after arriving, an election official informed the mayor that he was not permitted to be in the voting area and asked him to leave.

Ford then headed upstairs, DeSouza said, and posed for photos with members of the public.

The election official followed Ford, again asking him to leave. DeSouza said the mayor then met up with the elderly voter he had driven to the polling station and they both left.

In the letter to Ford, it states that he was also spotted at a polling station In Ward 7 on Friday and on Thursday, an election official told Ford to leave the Driftwood Community Recreation Centre on Jane Street, between Steeles and Finch Avenues, in Ward 8.

The letter says Ford reportedly spent a "considerable amount of time at the facilities, talking to voters" even after voting place staff requested that he leave.

The MEA does allow candidates to observe at polling stations, however, they are not allowed to interfere with voters, attempt to influence how they vote or ask voters who they supported. Candidates are also not allowed to have campaign material with them inside the voting area.

Ford, who was replaced in the mayoral race by his brother Doug Ford after being diagnosed with a rare cancerous tumour in September, is running for a seat on city council in Ward 2.

The mayor’s spokesperson Amin Massoudi said that Ford was just “volunteering” and trying to “help folks out” on Saturday. Massoudi also said that Ford was not handing out campaign literature or asking people to support Doug Ford.

When asked about the incident Sunday, Rob Ford said he just wants to make sure that the candidates get inside the polling station "safely."

"I’m going to go and I’m going to help people vote. That is what my job is," he said. “People want a lift, so I drop people off.”

Ford deflected questions about whether he thought it was appropriate to go inside the polling station.

Today is the last day for advance voting and as of Saturday, close to 125,000 Torontonians have cast their ballot. In 2010, approximately 77,000 voters turned out for advance polls.
