There's quite a bit of history with regard to the relationships between the different posts and how they're compensated. In the past there were products designed for letters, such as registered mail, for example, or packets, and the posts would pay each other compensation that would be reflective of a letter. There's been a lot of work going on at the Universal Postal Union to change that compensation model.
Canada Post, working with others, has been working hard to change that. Effective in 2018, the compensation that China pays industrialized countries will increase by a factor of about 100%, depending on the product.
To build on that, though, those products are really not well suited to e-commerce. They were designed with letters in mind. The e-commerce world is evolving to the point where delivery confirmation and tracking is a standard requirement. The e-commerce platforms are requiring that of their sellers. The products that were used by those sellers in China and were very inexpensive don't provide that basic need for the market.
It's interesting that what we've seen at Canada Post over the last year or so is a tremendous growth in a product that we introduced a few years ago that includes tracking. There has been a flattening and actually a slight decline in the volume of the untracked services. Those sellers are voting with their wallets, if you will, in terms of how they're moving to attract service.
We would expect that to continue. As a result, we would very much expect that it will become less of an issue over time, because the markets do require the features that come with the more expensive products, and those are the types of products that Canadian e-commerce sellers use as well.
