Food is limited to what is standard in rural Canada. Every town will have a greasy spoon, a Chinese restaurant, a fancier restaurant, a pizza place, and one or two fast food places.
If you ask around among locals you may be able to find some less common meats, which often come from hunting. Be aware that it is is also possible to buy illegal meat in this way, which is could result in some legal action. Outside of that things to look out for in summertime are church picnics or bbqs. Also the town of Wilno is known for its Polish fare.
