At best you could compare them to fox news, but they don't compare favourably even to that. They are admittedly maybe not quite as bad as Breitbart but it's close enough in my opinion.
CBC is definitely left wing[1], with a bias towards the liberal party (centre-left). Globe and Mail is centrist[0].
Highly partisan news is generally not respected for good reason though.
Be it Fox News lying and then claiming they're entertainment, not news, so they're allowed to lie; The Telegraph giving a soapbox to various climate skeptics and COVID deniers and having to retract them, or publishing flat out lies by folks like Boris Johnson; the Sun needs no explanation; Sky News Australia (same owner as Fox News) having a "Misinformation and conspiracy theories" section on their Wikipedia; etc.
