Repair and maintenance costs for the oil-rich province hit $13 billion in 2014-15, according to data released by Statistics Canada.
The figure covers the first nine months of the year.
Alberta has the third-highest rate of household income in the country at $37,000 a year.
The province also had the lowest unemployment rate at 4.6 per cent.
Statistics Canada says Alberta’s unemployment rate has fallen to 6.9 per cent, from 6.6 in 2013-14.
The Alberta government said the increase in repair and maintenance work is partly due to the province’s transition to a new model for managing its oil wealth.
