As I recall Ucluelet (only been there once years ago) has a scenic harbor so might be nice for photographing boats in the fog, etc. I've made several trips to Tofino (an hour north), however, and it is spectacular.
...my son is big on wildlife.
Years ago there was a wolf pack that hung out on the beach just south of Tofino. They became so habituated to humans (people threw them food, etc.) that they started to become a danger so the authorities removed them. Now I've heard that in just the last couple years a few have moved back in. You might ask around to see about photo opportunities. No grizzlies to worry about, but there are quite a few black bear on Vancouver Island as well
Not adverse to getting in a kayak for sure, wales should be migrating about then I hope.
In the summer you can rent kayaks and paddle around (with a tour or by yourself) the islands around Tofino, which are very scenic - highly recommended for photographing. However, March is a stormy month and I doubt that this will be possible then.
In addition to migrating gray whales, there may be resident orcas in the area as well.
