There is OOB for carriers and OOB for non-carriers. OOB for carriers is significantly more complex and resource intensive than OOB for non-carriers. This topic (OOB or to forgo) has been beat to death over the last 20 years in the operator circles; the responsible consensus is trying to shave a % off operating expenses by cheaping out on your OOB is wrong. That said it does shock me that one of the tier-1 carriers in Canada was this... ignorant? Did they never expect it to rain or something? Wild.
