I've had good luck with Yuasa in both Spyder and Harleys. I'm pretty sure the OEM is a Yuasa with Can-Am branding.
The correct battery for most Spyders is the YTX24HL. Avoid any that have a -BS suffix, as that means you have to add the acid and charge.
There is a battery finder on Yuasa's website: https://www.yuasabatteries.com/ Generally these batteries are cheaper on Amazon, but not always.
I just tried the Yuasa website search by vehicle tool. They don't list Can-Am. Am I missing something?
