Canadian Swallowtail Butterfly (?)

As far as I can tell this is the Canadian swallowtail although it is close to the Eastern swallowtail in appearance.

Evidently their ranges overlap in our area and extends across southern Ontario, and both species, as well as what appears to be hybrids can be found here.
If a Tiger Swallowtail is seen in late summer in Ontario, it is likely a second-brood Eastern Tiger , the Canadian Tiger only has one brood in the spring which is why I think it is a Canadian.

ID help would be appreciated.

It would be an Eastern Tiger Swallowtail down here. Usually Canadian Tiger Swallowtails are found perhaps starting at Owen Sound and northward, for example.

Okay this is weird; I’ll give you that right up front. We got Maggie from an animal shelter so we don’t know her background. We have found out that, if you don’t latch the bathroom door securely, Maggie will come crashing in to visit. She promptly climbs into your pants and makes herself comfortable. Now I don’t normally take a camera into the bathroom, however, this is regular thing with Maggie so, now you know the story. Sam, the black cat wants to know what Maggie is doing. Sam seemed quite upset over the blow to feline superiority.
