In general this is untrue outside of Quebec (and maybe Ontario). I'm in Vancouver and while there's some federally mandated bilingual text, the French-speaking population here is extremely low and day-to-day everything is English-only. Even local public sector things like announcements on the train. You're more likely to see signs in Mandarin than French.
However that might be because I am an anglophone from Ontario and my mind filters out the French language on signs if an English equivalent is present.
For a press release from a private company operating in Ontario there is no legal requirement to publish in both languages. Some companies might do so anyway if they have operations that are regulated by the federal government and/or they just want the goodwill.
Imported products have to meet Federal packaging laws, which do require both languages.
There was also controversy over proper names v. descriptions. "Macdonalds" is a proper name but should "Burger King" be translated to "Burger Roi"?
