The Leddy Library will host an event Friday morning to launch an exhibition recognizing Canada’s 150th birthday and the contributions of Poles to its development.

The exhibit, a collaborative effort with the Polish-Canadian Business and Professional Association of Windsor, explores three themes:

• contributions of Poles to Canada,
• contributions of Poles to the world, and
• why Poles are grateful to Canada.

Friday’s launch is free and open to the public. It begins at 9 a.m. on the library’s first floor with a reception to follow in its fourth-floor lounge.
