You can find a new one in repairing shop, Canadian Tire, Wal-Mart even Costco. There is much information available on internet.
OEM parts are good but aftermarkets could even better.
I don’t want to comments on each brands and stores, but just want to point out that many wipers under renown brands are just of normal or poor quality.

As many brands are 100% subcontracting their design and manufacturing process out, they have no capability to involve in those details.
