Are you measuring your parcel are you going by the dimensions on the box (which are often in inches) and converting to metric? The reason that I ask is that I used to use the box size stated on the box but noticed that when I do measure it is often a bit larger than the stated size.
Anyway, on the CP calculator the sizes you gave from Wpg to Toronto the small business discount says it is $17.64. When I entered a cm to each measurement so 36x26x11, the price was $18.64, a difference of .80.
I think that it is fairly safe to guess they measured it at the higher measurements.
You said you went with PP because you were worried about the extra charges but when you got charged extra a few months ago wasn't that with PP? I'm guessing that whenever we use our small business number I think that they will be charging us extra if they think the package is bigger, regardless of which online site we use. All of the platforms will charge you the volumetric size if you use a service that uses it.
Box dimensions printed on a box are usually of the inside space. Because the cardboard thickness can vary and from single wall to double wall, or for consistency when shopping from different box manufacturers, the inside dimensions is most important to fit the product.

Inner Dimensions? Or Outer Dimensions?
There are many ways you could measure a corrugated box. Here are helpful guidelines to accurately communicate your requirements for determining the right dimensions of your boxes. Use this info to work with case packing your boxes, and for handling your boxes with case formers, case tapers, and palletizers.
Corrugated case dimensions are stated in the order of length, width, and depth or height (L x W x H), referring to the opening of an assembled box. Usually, the length is the longer of the two sides, and the width is the shortest. The height (or depth if the box is on its side) is the distance between the opening and the opposite panel.
Case dimensions can be specified for either the inside or outside of the box.
Inside the Box
For an accurate fit of your product, inner measurements are considered.
When ordering or constructing a corrugated box, inside dimensions (ID) are used for measuring because the corrugated board thickness vary. A box constructed of C flute will have different outer dimensions than a box made from E flute material. When measuring the inside of an existing box, measure from the center of the score (fold line). Be sure to specifty the measurements as inner dimensions, for example: 24"L x 18"W x 14"H ID.
Outside the Box
For shipping considerations such as case forming and pallet patterns, outer dimensions are used.
When determining the right equipment to erect, form, tape, or glue your corrugated case, outer dimensions (OD) are considered. Outer dimensions are also used for shipping in general and pallet configuration purposes. Indicate that the measurements are outer dimensions, for example: 24.5"L x 18.5"W x 14.5"H OD.
