I would hope that your electrician would know the answer!

A licensed electrician should know. I'd be a bit afraid of using them if they don't. But If they don't, they should pop down to the building inspectors office to ask. You could go instead if you want

Install it per manufacturer's instructions and forget about it.

It is possible to even install regular receptacles Not to code in a kitchen while still following the installation instructions. It is also possible that the product will not meet specific requirements for a kitchen. For instance, regular Plugmold may be wired with 14 gauge wire inside, therefore only be rated for a 15 amp circuit, but the kitchen requires 20 amp. Or the receptacles are not tamper resistant. The modular parts do not necessarily come with GFCI or AFCI protection, yet the installation instructions do not specifically require either/both, or tell you when the NEC does. The installation instructions assume to a great degree that everything will be "standard", such as the bottom of the cabinets not more than 20" above the countertops. Your diagram shows 3 - 20 amp circuits just for that one wall, which means they are either attempting to guess at Canada codes ( which it probably falls just short on spacing or circuits), or they are way overdoing it for the US code, as only one circuit would be required for the receptacles on that wall, and another circuit on the sink countertop section. Are the under cabinet lights halogen, which will not meet Title 24, or are they LED? is there a remote transformer involved? There is not enough information here for the electrician to know anything for sure, but it will probably work, although you may have to pay for an extra trip or two for the electrician when extra parts need to be ordered to get the installation up to code for the specific situation.

I have never been impressed by the online information, or ease of finding the right information on the Legrand website. It would take me over an hour to get reasonably sure the system will work on the website, and about 2 minutes if I had the product in my hand.

There are dozens of codes that a kitchen electrical installation has to meet, and they do not all come in the box with a product, and not all products are designed to meet codes for all situations that someone might dream up to use them for.
