“Those other districts that are in the Lower Mainland, where the ridings are more marked by a kind of urban demographic and an urban sensibility, there is going to be, I think, a harder test for [the Conservatives],” he said.

I don’t see why… those ridings used to be de-facto Liberal and NDP.

Now, the ridings include strong Liberal and NDP neighbourhoods, meaning that Conservatives still have virtually no chance, but overall strong L or N ridings could go the other way, changing overall numbers of party seats.
