Comments & ID Thoughts
This spider was spotted on our canopy on our deck in Ottawa, Ontario.
I removed it to another location in our backyard without identifying sex etc.
Its 'body' from front to back is about 1/2 inch.

Pearl Beach, 
She’s a Lovely specimen. 🙂 Thank you for kindly relocating her. There’s one on my neighbors’s trash cart that I just realized I should relocate to protect her. Your deck canopy might have an Orbweaver egg sac on it. It would look like a cottony tuft. The eggs start development immediately upon leaving their mother’s body. They are freeze-resistant and the spiderlings emerge in the Spring. They disperse by air to go to spread to different locations.
