Canadian Army keeps option open to order more TAPVs

Several days ago I had an update on the Tactical Armoured Patrol Vehicle (TAPV) project. Deliveries are continuing to Canadian Army units and a number of TAPVs will be set aside for reserve force training.
The TAPV project, announced in July 2009, will procure 500 vehicles to fulfill a variety of roles on the battlefield. An option for up to an additional 100 vehicles is included in the contract. 
There were some suggestions that option was completely off the table because of tight funding.
