Armstrong signs 1-year contract with Canadiens
The veteran forward signed a $1 million, one-year deal with the Habs on Sunday.
Armstrong's two seasons in Toronto were hampered by injuries. The 29-year-old appeared in just 29 games last season, scoring one goal and three points.
Armstrong has a past history with Canadiens coach Michel Therrien.
He'll earn a total of $2 million next season - half paid by Montreal, half paid by Toronto.
