In Canada, anything is possible with the right brand of beer on the backseat and a friendly demeanor!
Jokes aside -- yeah. In a sticky spot, you're honestly never far away from a Speedy Glass type option (5-6 hour drive probably), but those companies would likely not be cutting anything as they'd just pull whatever is in stock. There are smaller-scale glass businesses, but these are not as common as they used to be in rural areas. In a pinch though, if it's reasonably rectangular and flat, a guy can do a lot with a jigsaw and some lexan to make the journey to the nearest bigger centre. I've had to do that before and managed it on a side window, but the only reason it was easy to do was because everything was flat, not curved. If it's curved, this gets to be a lot harder and so I had hoped the Gren would be flat but that info about it being curved is new to me and a bit disappointing (though I'm grateful for the info of course!)
