First of all, canola is our most important crop; it's our wealth creator. Canola has generated over $9 billion in cash farmers' receipts in the past three years, as you can see by my graph. In my own language, canola is the fuel for the velocity of money and for most of western Canadian agriculture.
Farmers have responded over the years to the profitability of this crop by increasing acres, making it Canada's most widely cultivated crop, and now we're seeing in excess of over 20 million acres of production in our country. Not only has production increased, but so have our yields by embracing improvements in cropping systems and genetics. Not only is the output of our crop increasing, but the yield per bushel in acres is also increasing. It's making us one of the most dynamic canola producing areas on the planet.
In my farming career, canola exports have nearly tripled, and here's a celebration of what can happen with open borders and strong trade relationships. Canada's rising production trend has been met by rising export demand mainly from China. We dare not invite China to deviate from its upward trajectory.
We've spoken about this lots at this committee, how important China is. If you look at the magnitude of the top 10 canola countries that we export to, we don't have a lot if we don't have China. Not only do 47% of our canola exports rely on Chinese purchases, but the exports to China are trending up. When we start looking at the exports to China that we've been seeing now, we're in the neighbourhood of 47%. This is where the hardships are starting to occur in our part of the world.
This uncertainty when things get complicated with China has resulted in an export pace slowdown that we're starting to see in these bulk trends. If you look at the five-year trend on on-farm canola, it's starting to trail behind the average, which means that we're starting to have buildup of inventories, and as a result, we're starting to have an impact on prices.
What I want to show you right now is that impact on new crop prices. If you look at this canola futures chart, the value of new crop canola has been reduced by about a billion dollars. If you look at this November 2018 canola contract, this is where new crop prices for canola—and we are about to plant very soon—are derived from. This is what you'd call in our terms a bloodbath. Uncertainty is risk, and risk is calculated into this graph.
I also want to talk very quickly about what's happening on old crop prices. I think that Mr. McClean did a very good job of that, but just to reiterate what he said, since December we've lost about $50 a metric ton on the May 2018 canola futures contract, and this is where the current cash prices are derived from. Since this fallout to our canola prices and the resulting economic pain, the market estimate impact to the farm gate I have estimated from trade sources at $340 million, and this is what the crop in canola farmers has been since it dropped in early December.
When you look at this new price chart, this is what Canadian farmers are looking at right now while trying to make planting decisions. Where I come from, canola is the economic engine of our family businesses and the local economy and fundamentally the most important component of the multiplier of our commerce. It is imperative that Canadian canola, seed oil and meal have access to the Chinese market. Relationships need to be restored immediately.
I am hopeful that this group truly understands the importance of the situation, but I want to remind you that canola is the foundation of our way of life. It's what drives our investment decisions and our capacity to finance and operate our businesses. It has attracted huge domestic and international investments both up and downstream through the value chain. All of this depends on trade. There are some risks of countries like China creating alternative supply channels with other suppliers, and this is coming at a time when the overall economic environment and reduced profitability are already challenging the Canadian commodity agricultural portfolio.
We need this market, ladies and gentlemen.
This is not the first time in my 20-plus years of farming to experience trade concerns and trade conflict. The Chrétien, Martin and Harper governments also had to navigate through some uncertainty in international trade; however, I cannot remember so much conflict of the major crops all at once.
Our Canadian system is far from broken. I think it may be just our approach. We have some of the most talented deputy ministers, trade negotiators and support staff on the globe. They have represented us well in the past and made us all proud.
I'm reaching out to this group to please think of this issue not as a file or a briefing note but to remember that this is our livelihood in western Canada. I strongly encourage this committee to work with industry and commodity groups, but I also challenge this committee. I feel it's time to flip the switch to strategic thinking and political savviness.
When we check the science box, which we've talked about at this committee, we're going to check that box about what this trade dispute is all about. When we do that, we're going to get refocused. As we all know, it is not about science. We all know it's about politics.
This is a disturbing trend, as we seem to have one strained trade relation after another, as it appears that the dominoes of strong trade relationships are starting to fall, and farmers like me are paying the consequences. China played its big card, the canola card. This card hurts, and it hit us fast and hard and it was deliberate. This has been caused by politics, and it can only be solved by politics. Farmers like my family and me live and breathe in an environment with so much uncertainty. Our success relies on facets like trade to operate in a stable and predictable environment. This all starts with our government: We need strategic engagement right now at the political level. In closing, farm families need to be reassured that their elected officials understand the complexity, severity and urgency of the situation.
I thank the committee for your time.
