For HouseholdSpend 2019, why is there so much change in the Recycling fees (HSME019) and other general expenditures (HSME020) variables compared to last year?

There are a couple reasons for the significant inter-vintage change for these variables. First, there is a magnitude effect at play, both these variables have very small aggregate dollar values so even small absolute change in expenditure will produce sizable percent change. Second, these variables are based off the diary portion of Statistics Canada’s Survey of Household Spending. Variables created from the diary tend to be a lot more volatile year over year.
