Food prices are supposed to rise in Canada even more in 2016 than in 2015, with the falling loonie an important factor.
Canada is very exposed because so much of our produce is imported. However I've also noted a significant increase in the price of pasta and baked goods, although most wheat and other grains are grown in Canada (hey, even Italian pasta comes from Prairie high-durum flour). There has been a huge increase in the prices of goods supposedly on "promotion" or "sale", which is so important for people with very limited budgets who can only eat anything nutritious by watching these like a hawk, though the rise certainly has an impact on all working-class families and people living alone.
I note that almost all the quinoa (just as an example) that I see in shops is imported from Andean countries, though it has been successfully grown on the Canadian Praries. What gives?
As for some of the advice in the article, I always look at frozen produce, which has improved in quality, but find that frozen vegetables have also been VERY expensive recently.
I already do pretty much everything else the article advises.
