I reside near Hanover Ontario and six and a half year's ago I erected a tarped structure 30' x 40' which was sold to me by Calhoun Agri Services.

The structure had a clear strip down the center of the roof for light.

This year I noticed that the seams were letting go on the stripe

I contacted Calhoun and received no reply.

Three week's ago the structure collapsed and now 6 1-2 years latter I have no building.

I called Calhoun again and no one returned my call's

I drove to their office and spoke with them and they told me that this type of structure should never have been consturcted in this area and yet the drawings are stamped by a eng. and sold to me for erection in this area.

I recall conversation with Mr. Calhoun at purchase about these structures because I was sceptical and he said I would and or should not have trouble with the tarp for 10 or 15 years let alone having the thing collapse.

Subsequently Calhoun will not do any thing about it.

Foolishly I erected another one of their structures almost 3 years ago but will never use them again
