Answer:
Pinus resinosa has its common name as the Red Pine. According to my " Hilliers Manual of Trees & Shrubs " it's a - quote, "Small to medium-sized tree of rather heavy appearance, with a broad , conical head of branches. An important timber tree in North America. Native to Eastern Canada & the North-Eastern USA. "
'Small' in the above book = Up to 10 metres ( up to 35 ft )
'Medium' in the above book = Between 10~18 metres ( 35 to 50 ft)
So I'd ' guesstimate ' - 40 feet , max.
