No. Della Falls has a total height of 440 metres. Many sources say it is the tallest waterfall in Canada, but that isn't true. Della is number 16 on Wikipedia's list of tallest waterfalls in Canada and 23rd on the World Waterfall Database's list. Since most of Canada's tallest waterfalls are located in British Columbia, it's not even the tallest waterfall in BC. There are several ways to count the height of a waterfall. Some measures count the overall height while others count the longest single drop. Della Falls is not the highest waterfall in Canada by either of those measures. However, it is still really spectacular!
