Yes, but the uk doesn’t have the spare non urban centres
There is plenty of space in the north of the UK, where the climate is far milder than in the immense majority of the territory in Canada.
Windsor to Montreal is also really one big city. Unsurprisingly since it's one of the areas with relatively mild climate, compared to places like Nunavut.
Space is not the problem. The problem is that we welcome over a million people coming to the country per year and we are not building nearly enough housing for them.
I've heard of hunters placing wires strung across MTB trails at neck height. In Spain several people have died or become tetraplegic due to them. You can't see the wire in time to do anything about it.
