They are the buildings and structures where history was made — literally. But sadly, many of these important edifices are badly in need of repair. The following 10 historic structures were named the "most endangered" in Canada according to a list released recently by the National Trust for Canada. The goal of the National Trust's endangered heritage list is to raise awareness about the importance — and fragility — of our built heritage.

The selection—presented here from the West coast to the East coast—was compiled from the results of the National Trust’s call for nominations as well as those stories and news items followed throughout the year.

This year's list includes:

Point Grey Secondary School, Vancouver
– Seismic mitigation program poised to reduce historic school to rubble

Peace River Valley, Northeast British Columbia 
– Hydro power trumps aboriginal and natural heritage

East Coulee Truss Bridge, East Coulee, Alberta
– Trestke Bridge needs new lease on life

Our Lady of Assumption Church, Windsor, ON
– Hope remains for future of historic church despite fundraising roller coaster ride

The Barber Paper Mill, Georgetown, ON
– Stakeholder impasse threatens industrial heritage site

Central Experimental Farm, Ottawa
– Federal government plays fast and loose with a national historic site

Hôpital de la Miséricorde, Montreal
– Institutional landmark in need of revitalization
