It is a good practice to order your credit report every year. You never know what errors lurk in them. The first time I ordered my credit report, I found that my bank still had a lien on my car though the car loan was long paid off.

The two major credit bureaus in Canada (Equifax and TransUnion) will send a copy of your credit report for free if a request is made by mail. The application forms (available here and here) should be accompanied by two pieces of identification and are usually processed in 5 to 10 days.
