This is a great question.
A modernized grid is be an essential ingredient for the future. There are major investments being made by all utilities across Canada to improve the distribution grid, and improve the transmission systems as well. Overall, we are privileged as a developed economy to have a good system, but that current system does not have all of the characteristics that are needed in the future. For example, as more and more distributed energy resources are integrated into the grid, then two-way power flows will happen. That is, if you have a large solar array on the roof of your home, power will be going out through the grid, not into your home. It's the same thing at any scale, including businesses and institutions. The grid is not built for that.
Second, it is also not reliable enough for the demand of our economy. We are more and more dependent on a reliable grid, and we'll be even more so as, for example, we get electric vehicles. Furthermore, every time there is even a short momentary outage on the grid, a few seconds, you have to reset the clock on your microwave, but more importantly in terms of generation, your solar panel on your roof will go offline for minutes. Therefore, we are in a situation where the lack of reliability is actually causing our new, distributed generation to go offline. Obviously, that's not desirable.
In summary, it's in a relatively good state across Canada, but it's not built for the future.
