Eidos Montreal is going to double its size by expanding to 680 employees. The move is part of a plan in conjunction with the Quebec government that will see the government fund the majority of the expansion plans for Square Enix.

The deal, according to what has been reported, has seen the company seeking about $2 million CDN for the government to kick in to make this actually happen. If it happens, it would mean 100 jobs during 2012 and an additional 250 more before the end of 2015.

The decision has been made easier by the generous tax credits from the Quebec government. Why Square Enix is expanding is due in some part to its recent success with the recently released Deus Ex: Human Revolution, where Quebec tax credits are said to cover about 40% of production costs.

If successful in this expansion, the move would make Eidos Montreal the third largest studio located in Montreal, followed by the Ubisoft 1,200 employee facility and Electronic Art’s 800 employee facility. Currently, Montreal is quite a hotbed for gaming development.

Square Enix has not commented on what plans might be in store for the Montreal studio expansion. As far as what franchises they might be working on at this studio in the future or what development plans might be, there has been no official comment.
