To our customers and suppliers,

Image Inspection Services Ltd. has taken pride in serving our customers for 36 years. We started with very humble beginnings and grew into a name that has successfully sold equipment around the globe.

However, these past couple of years have been very difficult and have impacted many businesses. So, it is with a heavy heart we too have decided close our doors. Due to unforeseen circumstances that are beyond our control it is no longer feasible for us to continue in business. Our official end date for being in business will be March 31/22.

It will take some time for us to make adjustments on the accounts, clear out equipment, machines, tools, etc. If you have any questions about some stock items that we may still have you can reach out to us.

We’d like to thank our loyal customers and appreciate our suppliers for years of service. It has been an honour to serve you and we wish you every success.

Paul and Denise Varro
