Pity you don't actually know all that much about how Canadian politics works. Otherwise it might actually have been helpful.
In Canada what you're referring to is called the "legislature", not the "government". The Government of Canada is a specific executive body formed by the party or coalition of parties that holds the most seats, provided they can pass a confidence vote in the House of Commons. It has the power to make Cabinet appointments, propose and execute budgets, and set the legislative agenda. As a member of an opposition party, Angus is categorically not a member of the body known as the Government of Canada (colloquially, the Canadian Government, or Federal Government).
You're also deeply misunderstanding the nature of "official party status." This only matters for the purpose of election laws; it defines access to funding, who gets air time and invites to debates, that sort of thing. Once the legislature are seated, it has no impact. From that point on you only have "The Government", "The Official Opposition" and "The Parliamentary Opposition." The parliamentary opposition is comprised of all MPs, including independents, who are not members of the government. The official opposition is a subset of the parliamentary opposition comprised of the members of the largest opposition party. This status affords them certain legislative priveliges. For everyone else, their status within parliament is completely equal. A member of the NDP has no more rights and priveliges than an independent or Green Party MP.
As a member of the parliamentary opposition, not even the official opposition, Angus is about as low on the totem pole as it is possible to get. He is, categorically, not a member of the Canadian government (unless you're foolishly attempting to force US American definitions onto a non-US American political system), and you'll notice that I never disputed that he is a lawmaker, I just pointed out that this wording is about the most generous definition of his role in our political system that the writers were able to find.
None of this is any disrespect to Charlie Angus. I like the NDP. I wish more people voted for the NDP. But any views he expresses really do not reflect the position of our government, or anything remotely like it in most cases.
