Subsequent Events [Abstract]
Subsequent Events [Text Block]	18. Subsequent Events The Company has a subcontract agreement with Black & McDonald Limited (“B&M”) to provide engineering and procurement services under B&M’s master services agreement with Ontario Power Generation (“OPG”). The Company understands that in October 2014, OPG provided to B&M notice of default and termination of a large purchase order from OPG to B&M with respect to which B&M had engaged several subcontractors, including the Company. B&M notified the Company that it is disputing OPG’s default claim on this purchase order. As of September 27, 2014 the Company had outstanding accounts receivable to B&M of $5.6 million under the disputed purchase order and, including such amount, a total of $15.8 million of outstanding accounts receivable to B&M. OPG has indicated to the Company that it will not make any further payments to B&M on the project in dispute. The Company has received notice from B&M that while B&M disputes OPG’s assertion it is in default, B&M believes that in the event that it is in default under its agreement with OPG, then the Company may also be in default under its agreement with B&M. The Company does not agree with this assertion. The Company does not believe that any of its account receivables with B&M have been materially impaired and believes that its accounts receivable with B&M remain collectible, subject to existing reserves. However, it is possible that a protracted dispute between OPG and B&M may impact the Company’s ability to collect its outstanding accounts receivable in a timely manner.
