Since 2010 CastleTech has served Canadian companies. Located in Guelph with datacenters in Guelph, Toronto, and Chicago, we are a friendly, dedicated consulting firm who believe in strong partnerships, not strong billables. Probably why we have never lost a client.

"CastleTech did an excellent job, displaying both skill and professionalism. The networking project was completed on time and within budget! I would recommend CastleTech to anyone seeking assistance in the future; they were an invaluable asset to have."
