We are service organization that specializes in file system installation for various filing system dealers throughout the US. We have been hired to install a file system in Canada. This job will take 3 days to accomplish with 3 American installers (US passports). What steps do we need to take to aquire the proper documentation in order to do this installation?

Thank you

Based on the information supplied, a Labour Market Opinion will be a necessary first step. With a LMO approved, the work permits can then be sought either through a visa office in the USA or at a port of entry. If the installation work is part of the sale of such, then provisions exist which may allow for exemption from this process in some cases; more details on the case would be needed to accurately determine that.
