Just wanted to update my own post. Before our last trip in 2009, I called my DH's employee insurance provider to inquire about the out-of-country health coverage. The Representative went over the details of the policy and even directed me their website were I could log in and print out a certificate with the insurance details (policy #, emergency 24 hr telephone number..).
In preparation for our upcoming trip, I logged into the website again to print out a new card even though I technically did not need one because the old one did not have dates on it. When I could not find what I was looking for on the website, I called the insurance company and was advised that my husband's plan no longer covers out-of country medical expenses. After checking with my husband's co-workers, it seems that no one was aware of this change. In fact, one co-workers just got back from a Carribbean cruise with his family of five and assumed he had coverage through work. Another co-worker just returned from a 3 week holiday in Florida and spent $600 on seeing a doctor for his daughter's ear infection, assuming that he would be reimbursed through the company insurance.
The moral of this story is that it never hurts to double check your coverage before you leave. I purchased health insurance today through Scotiabank for $86, so everything has turned out o.k. for us, but I am so glad that I double checked before we left
