The US does that too in most places. 5+4 zip codes. It's still not enough and suffers the same precision issues and we (the USA) are woefully ill-prepared for the housing build out boom that will happen in the next decade. We need a better system. We will exhaust our zip codes like we have our IPv4 addresses.

Zip codes don't need to identify buildings, they need to identify post offices (and with +4, mail carrier routes).

That's a much smaller number.

Oops, right, 5+4, not 9+4. Counting is hard.

But yeah, what I meant to express was that Canada doesn't have a lower-precision version in regular use.
