So the reason that pet sales are banned in Vancouver is that inhumane manufacturing processes (breeding mills) exist.

A fascinating line of argument.

At this rate, then, Vancouver should ban the sales of running shoes, clothes and pharmaceuticals, since inhumane manufacturing processes exist out there for all of those products.

Yup, don't let anyone in Vancouver buy another running shoe, shirt or pill in that city until the brave social justice warriors engineering Vancouver have solved the worldwide problems in those areas.

And maybe after they have finished curing the world of probelms in the area of dog, running shoe, cat, pill, tee-shirt, dress and rabbit...

... they could do something about something useful about something wildly outside of the purview of city concerns, namely, um, the prohibitively expensive house situation in Vancouver...
