Just because you live in the Netherlands doesn't mean you don't have to pay taxes in Canada. Depending on your income and things like assets in Canada, amount of tax you pay in the Netherlands vs tax you would have to pay in Canada you may very well owe taxes in Canada. The only way to avoid this is to complete a form and submit to the Canadian government (can't remember what it is called) that indicates you are no longer a resident in Canada (don't worry, doesn't affect your passport!). To prove this you have to show you don't have property, income, etc in Canada.
I wouldn't skip doing your taxes in Canada out of convenience. If you ever go back to Canada and have to file taxes there will be a big hole in your history and likely an audit to follow.
