In the heart of Paris is the Arlington Hotel, recently restored, somewhat upscale (though still affordable) with a nice restaurant on the main floor.

There are at least eight B&B's in Paris alone, of which the River Ridge Bed and Breakfast, just around the corner at 232 West River Rd., is certainly the closest. Another that's very nearby (and recommended) is Behind The Pines B&B, at 1 Homestead Road - Mike Sywyk, (519) 442-1740 / miketiques@aol.com. bbcanada.com lists seven Paris B&B's, along with two more in nearby Ayr.
** Remember that many B&B's have restrictions on the hour by which patrons must arrive for the night - be sure to discuss this with the management in advance! **
In Brantford (about 20 minutes away) are three well-known chain hotels -
