OTTAWA - Prime Minister Stephen Harper has a suggestion for Canadians looking for a New Year's resolution for 2013: go easy on consumer debt.

While most Canadians are living within their means, they need to be thinking about what could happen if interest rates suddenly rise, Harper told Global News national anchor Donna Friesen in an interview.

Statistics Canada reported earlier this month that debt levels were at their highest yet — for every dollar of after-tax income Canadians bring home, they're borrowing more than $1.64.

"I'm convinced we're now seeing a moderating trend in this, and I think it'll start to turn down in the next year and a year or two, but we continue to urge people to have caution because eventually, interest rates will go up," Harper said.

"You should be asking yourself, 'If interest rates were a couple of points higher, can I really afford the debt load I'm taking on now?' And so we just urge people to be cautious on that."

Mortgage debt is the primary driver of higher consumer debt loads after years of low interest rates.

Statistics Canada said that between July and September of this year, households borrowed $27.3 billion, $18.4 billion of it in the form of mortgages.

Consumer credit levels increased by $7 billion to $474 billion.

Harper's comments echo concerns raised in recent months by both Finance Minister Jim Flaherty and Bank of Canada governor Mark Carney that debt levels are getting too high.

"That’s why the government is taking some measures to provide incentives to households not to borrow quite so much," Harper said in the interview.

"But you know, the fact of the matter is, this is (a) decision that households have to make for themselves."

Mortgage rules were tightened over the summer, including a reduction in how long Canadians can borrow the money for their house.

The housing market cooled off slightly afterwards and the Canadian Real Estate Association has said it expects that to continue into next year.

Harper says Canadians also need to look at the long-term picture, especially as baby boomers head towards retirement with uncertain pensions.

"What I'd say to all Canadians is balance your debt levels, balance your borrowing, and balance your ambitions in terms of house ownership with some savings as well," he said.

Meanwhile, don't panic about the world, Harper said.

While things may look gloomy in the U.S. and Europe, Canadians need to focus on their own prosperity, he said.

"Let’s focus as a country, and focus as an investor or worker, on what you can do to make your job and your company more competitive in the years to come," he said.

"That’s what we're focused on."

  • Have A Specific Goal

    For example, you may say "I would like to lose some weight this year," but it would better if you said, "I want to lose 50 pounds this year," says Diane Dressel, a registered dietitian at the <a href="" target="_hplink">Mayo Clinic</a>.

  • Talk To Experts

    With the right program, 50 pounds can be realistic. Ask the program you're considering what the average weight loss among participants is in a year. Depending on the program and its weight loss approach, you might need to set a smaller, more doable goal.

  • Set A Target Date

    It doesn't have to be the magical date of "January 1." Look ahead to see which date or plan will support you the most -- and be realistic.

  • Stay Positive

    Behavior only changes from the positive. Remember there are programs to help you accomplish your goal. Also look ahead into the future, make a list of the "real" reasons you want to lose weight (your health, your family). When you lack reasons to change, it is easy to fall back into old habits.

  • Avoid Temptations

    You will need to change your environment to help with your weight goals. Get rid of food that won't help you realize your goal -- this should be part of your planning.

  • Tell Your Loved Ones

    Changing your habits for good may affect your inner circle of friends. Let them know what you're trying to do, and enlist their support in helping you achieve your goal.

  • Don't Give Up

    Give yourself another chance. Most people slip up at some point. The people who are successful are the ones who get back on track. Look at how many days you still have left in the calendar year and see what you can accomplish before the year is up. Keeping your goals is all about commitment, she says.
