The Canadian Regulatory situation appears to be something like this –
The Canadian Food Inspection Agency (CFIA) and the Health Products and Food Branch (HPFB) of Health Canada are both responsible for food packaging issues. Health Canada sets standards and evaluates food packaging against these standards. Packaging requirements at federally regulated packaging facilities are enforced by the CFIA. As a best practice, Health Canada recommends that foodpackaging companies obtain a Letter of No Objection from the Health Protection Branch for any packaging that may come into contact with food. (It is important to note that a Letter of No Objection does not absolve the packer from liability, should there be a failure in package design leading to the contamination of the food product.)
To obtain a Letter of No Objection, detailed information about the printing and packaging processes is required, along with representative extraction test data, where possible. If the food package has a functional barrier between the food and the printed ink film or, if the ink is completely dry and there is no ink setoff during stacking/nesting of the packages, then the package is considered to have ‘no direct food contact’ with the ink film and a Letter of No Objection is not required.
More information can be found in the Canadian Food Inspection Agencies Guidelines for Submissions, Reference Listing of Accepted Construction Materials, Packaging Materials and NonFood Chemical Products.

PS - Note that in the US, the conclusion/answer to the OP is particularly interpreted in respect to food additive considerations, eg via migration data. Some further digging is required to determine whether Canada utilises similar notions / quantitative limits.
