Your best business development ideas in Canada

1. Do not go into any kind of business that offers a service unless you can provide the service over the internet. You'll either be limited to how much of the service you can provide by yourself or have to cope with unreliable employees and mountains of paperwork.
2. Stay away from renting any kind of space to run your business. You'll be stuck with a lease, a continuing overhead, and a location that may not suit you.
3. No-one can say what would be the best business for you to run  but here are some criteria to apply.
(a) Run your business from your home but make sure it isn't disrupting the neighborhood - no noise, no parking problems, no other physical intrusions on people nearby.
(b) Check into the local bylaws and licenses for running a home-based business but be aware that many such businesses aren't licensed.
(c) While you can claim some of your living space as a tax deductible expense, don't do so if you own the home. If you do, any tax-free capital gains on the house will be reduced by the percentage you've already claimed.
(d) You must have a web site. Offer something you don't have to make yourself, that can be sent easily by mail or courier, that is likely to create repeat custom, doesn't need you to carry a large inventory or take up a lot of space, Above all, it should solve a problem for the consumer. Remember you are selling benefits, not features, and ask yourself why the customer should buy what you're offering. Pay close attention to customer feedback and watch the competition
There's a lot more I could tell you but here's one final piece of advice. Do not start a business selling something you don't know anything about. Just because someone else tells you it's a great idea, doesn't mean it is. Use the criteria above and do your own research.
Best of luck.
