That same month (April 2002), Wolverine played a large role in a five-part story called Enemy of the State II in the Black Panther title. Alpha Flight, and therefore Guardian, also popped in briefly.
Why are Wolverine and Alpha Flight involved at all? Seems Black Panther produced old paperwork which reveals that an island on Lake Superior actually belongs to Wakanda and he wants it back. The following partial page is from issue 43, the third installment in the arc, and the cover to which can be seen at above left.
Highly unlikely; that Mac died almost three years before in Wolverine #143. The "real" Mac wore it for a while too; I believe he ceased to do so in Scott Lobdell's brutally painfully dumb third volume of Alpha Flight from 2004. At least something good came from that atrocity.
Back to Panther #43...The Wakandan king and Wolverine do end up meeting with Alpha Flight. Showing a little consistency and continuity, Wolverine even takes the time to ask Heather how she is and she updates us on her pregnancy. Nice touch. Then they get down to business.
Unfortunately, that's about the extent of Guardian and Alpha Flight's involvement. They do appear in one poorly drawn panel later in the story to interfere with Iron Man's plan to stop Panther's plan, but that's it.
Still, it's nice to see the team's existence acknowledged when something major happens in Canada (and not show up to be jobbed out), even if a blurb in issue #42 makes reference to "Sault Saint Marie".
