Welcome to the forum.
Apparently you have enjoyed yourself like a globetrotting grasshopper and have essentially nothing to show for the past ~15 years. Well, you are not alone. And at least you've finally realized the need to provide for your future. Better late than never!
You still have time to save, invest and otherwise plan. If you can be happy with a modest lifestyle, an early retirement is probably still possible for you, if you aggressively ramp up your savings.
You've got a couple of things going for you: (1) you have no children, so that's one expense that you won't have to cover; (2) as a Canadian your health insurance is covered, so that's another savings.
You might get some benefit from these books:
- Derek Foster, The Lazy Investor: Start with $50-- and no investment knowledge (2007);
- Derek Foster, Stop Working: Here's How You Can (2005);
- Dianne Nahirny, Stop Working - Start Living : how I retired at 36, without winning the lottery (2001);
- Alan Dickson, Free Parking: a second look at financial planning (2001);
- Alan Dickson, Advance to Go: the road to a rich retirement (2003);
- Joe Dominguez, Your Money or Your Life: transforming your relationship with money and achieving financial independence (1992).
None of those titles are without flaws, but they should be of some help.
Finally, note that if you spend all or most of the balance of your working life overseas, you will have little or no CPP or OAS entitlement: that is an incentive to stay put for the rest of your career. Most publicly-employed Canadian teachers have generous private pension plans, too.
