There was some argument over that pipeline puncturing by the city crews - they were following a map provided by K-M, and were following it correctly - the map was apparently wrong.
That incident - which produced a literal gusher of oil - totally ruined many houses in the area, which had to be bought out by the city. And land in Metro Vancouver isn’t cheap.
I’m not anti-oil, but there’s more to that story that should be considered.
Just like in the US, Canada has a "call before you dig" program.
Make the call and they will come mark the location of their buried utilities and lines. That puts the responsibility on the owner of the buried lines if wrong.
If you dig without doing that call, you take responsibility for what you hit, same as in the US.
