Okay. Thank you very much. Let me know if there's a problem.
I'd like to thank the committee again for the invitation. I really appreciate it.
In my research, I look at Canada's energy future from both an environmental and a Canadian economic perspective.
I have noticed over the last 30 years or so that Canadians are getting richer all the time in terms of gross domestic product or average household income. As Canadians, we've been continuously getting richer and richer. Obviously, this wealth is not evenly distributed, but we are seeing growing wealth across all segments of society. Unfortunately, at the same time, we have a climate crisis that is creating climate challenges, an increase in greenhouse gas emissions and a national debt that has been growing steadily since 1990. This debt has nearly tripled as Canada's population has grown from 27 million in 1990 to 40 million in 2023. Our debt is growing at a much faster rate than the population.
In addition, despite the fact that we are richer, we are taking on more debt and polluting more. This is something that is very difficult to understand because, normally, by being richer, we should be able to take better care of the environment and not get into debt. I say that because we are taking on debt as a society at an unprecedented rate.
I think the federal government's budget could be an extremely useful tool for reversing these trends. Although I do want Canadian society to continue to get richer, we want to avoid getting into debt and polluting.
When you look at Canadian households, you can see that they have been getting richer and richer over the last 30 years, and I've included some numbers in my brief that clearly show that this applies to all categories. Those households have three major expenditure items: housing, which represents about 30% of expenditures; transportation, which represents 15% or $10,000; and food, which also represents 15% or $10,000 on average. There are problems in all three sectors.
Let's start with the housing sector. Again, we are seeing worrying trends that are leading us to a housing crisis as well as an energy crisis. We have to heat our buildings, which is costing Canadian households a lot of money. Householders often complain, despite their increased wealth, that money is tight.
However, if we look at the statistics for the past 20 years, we see that the size of Canadians' homes continues to increase. I would even say that we've been seeing this trend for 30 years. In 2000, the average home in Canada was 48 square metres. In 2021, it's almost 59 square metres. That's per Canadian. This means that in 21 years, every Canadian's home, on average, has gained an additional 10 square metres of space.
According to a ranking by the Organisation for Economic Co‑operation and Development, Canada has the most rooms per person. There are 2.6 rooms per person in Canada, whereas in the United States, there are 2.4 rooms per person. That means we have more and more empty spaces, which are expensive to heat, build and cool. In addition, these spaces are expensive to equip for goods and services, because we want to have televisions and other equipment in these rooms.
All that to say that when we are facing a housing crisis and the size of our homes is increasing, and when we are facing a climate crisis and we should be using less energy, building more housing and more large homes is not sustainable.
We must use the budget to reverse this trend of homes continuously getting bigger. My proposal would be to consider including a tax in the budget that would penalize those who have large homes.
Let's move on to food, the second item. Food weighs heavily on household budgets. In addition, we also see obesity problems in Canada. Statistics are constantly showing that people are overweight, which is obviously the result of an imbalance between the calories consumed and the physical effort made. It costs society a lot of money, because being overweight and obese leads to health problems. It costs households a lot of money, because they have to buy expensive food.
We also see a pollution problem related to agriculture, which is responsible for 10% of greenhouse gases in Canada. This sector is producing more and more greenhouse gases. However, as you know, Canada's goal is to achieve net zero by 2050. So we have to reduce greenhouse gas emissions.
It is inconceivable that we are spending money today to create pollution and contribute to obesity, which in turn stresses the health care system. This means we have to find ways through taxation to ensure that Canadians eat better and reduce their fat, sugar and salt intake to improve their health. I therefore invite the committee to look at making changes to the taxation system based on that.
Finally, we are noticing concerning trends in transportation. Canada has an ever‑increasing number of vehicles per 1,000 inhabitants. We went from 495 vehicles per 1,000 people in 2000 to almost 600 in 2021. As a result, there are more and more vehicles per person and those vehicles are getting bigger and bigger. In 2000, sport utility vehicles accounted for 30% of all vehicles; in 2021, that percentage rose to nearly 50%. Not only do these vehicles cost more and weigh heavily on household budgets, but what impact are they having?
