Plevna/Tomvale Airport (TC LID: CNA9) is located 3 nautical miles (5.6 km; 3.5 mi) south of Plevna, Ontario, Canada.

It was established and built by Kathleen and Claudio Valentini in 1989 on a property previously owned by Edmund and Florence Weber, who farmed the property for 75 years. It is privately owned, and prior permission is required to land there. Tomvale is also the home of Tomvale Software, which produces Tomvale Ground School software, preparing pilot candidates for the Transport Canada and Federal Aviation Administration exams, as well as unrelated software. The name "Tomvale" is a portmanteau combining the names of the family.

Tomvale is situated on Farm Lake which is part of the Mississippi River system in Ontario. The north shore consists of twenty waterfront properties, some of which are owned by pilots who make use of the airport. Although a water aerodrome does not exist on the lake, aircraft may land on the lake and obtain some limited services from Tomvale. The waterfront community is accessed via Farm Lake Lane which is an easement over Tomvale property.

Tomvale has a possible impact crater at the end of runway 05.
