OH, do I feel stupid
I plugged the dimensions and weight
into the USPS calculator again, only using US to US zip codes. Rather than trying to ship into Canada.
Lo and behold I can get it shipped to one of the members just across the border for less than $20 USD insured.
The problem is with Canada post. The limit up here on length is 2.0 M or 78 3/4", which is less than a 7' (or 86") awning
One of my favourite TV lines fits this situation perfectly.
