Canfield says she received a letter from the Obama campaign, inviting her to attend the event at James Day Park. She doesn't know how she will be involved, but says she is "very excited" to finally meet Mr. Obama.
Canfield has been a symbol of uninsured Americans for the President during his health care battle. She made headlines two years ago when she wrote Obama after her leukemia came back, and she did not have health insurance. President Obama says it was because of her letter that he created the health care bill.
Obama's two-day 'Betting on America' bus tour runs through the political battle grounds of Northern Ohio and Western Pennsylvania. He'll stop in Maumee and Sandusky before his appearance in Parma Thursday night.
The President is expected to talk to voters about his efforts to fix the sluggish economy and get the unemployed back to work.
Parma police were patrolling James Day Park ahead of the President's visit, to ensure safety at the event.
If you have a ticket and are planning to attend the event, make sure you arrive early. Seating will be limited, and those in attendance will have to go through security checks.
The President is expected to arrive at James Day Park at 7:15 p.m.
