Is images.google.ca Safe?

This is a very good website but even with the filter on strict, when I search "marsh" (I need a marsh photo for a science video project), I get adult pictures of Jodie and Michelle Marsh (usually) half naked, even if the filter is on strict. And as stated in another comment, the filter is easily turned off by a child. The filter control is seriously directly under the search bar when you're on the results page. You don't even need an account for google to turn the filter off!

I was googling castle pics here: http://images.google.ca/imgres?imgurl=http://rolfgross.dreamhosters.com/Georgia-Web/Khintsvisi/1980KhintsvisiApseofRuined-12thcent-Church.jpg&imgrefurl=http://bbs.keyhole.com/ubb/ubbthreads.php%3Fubb%3Ddownload%26Number%3D725213%26filename%3D1215772-RomanesqueArchitecture.kmz&usg=__13QWuVumPC3e05N-wJXrVc5-i3c=&h=624&w=413&sz=48&hl=en&start=167&um=1&tbnid=KmssveeqWzO7TM:&tbnh=136&tbnw=90&prev=/images%3Fq%3Druined%2Beur and one came up on this site. I tried to open in new tab but the site wanted to download a kmz file. Not going to happen! Didn't do it of course so don't know what the end result would be hence category "other". But I wouldn't trust a site that does that.

Almost perfect, the only thing is that the filter can be turned off very easily, and even if the filter is by default, you can get some inappropriate result for kids, and even very disgusting pictures if you are not lucky. But in general, it's a great site.
