Playing with future Maple Leafs teammate Harvey "Busher" Jackson, he achieved staggering scoring numbers, leading the Marlboros to the Memorial Cup playoffs in 1928 and 1929.

[4] Signed the next season by the Maple Leafs with Busher Jackson, Toronto manager Conn Smythe paired the two with former farmhand Joe Primeau.

According to another league rule, any player jumping on the ice while his team was at full strength received a major penalty, and Irvin had Conacher do so, thus triggering his automatic suspension for a game in which he could not play anyway.

[11] A broken collarbone sidelined Conacher for weeks in the 1933 season[12] - the only one in a six-year stretch in which he failed to lead the league in goals - but he was once again named to the Second All-Star Team at right wing.

Things would change in 1937; Primeau and Clancy retired, while Conacher broke a wrist in training camp, an injury initially thought not serious.

[14] The Detroit Red Wings, seeking to improve their team, purchased Conacher in the fall of 1939 for a sum reported to be $16,000, and contingent on him remaining in good health.

The Generals finished in second place in both 1946 and 1947 - coincidentally, losing in both seasons to the St. Michael's College Majors, coached by his old linemate Joe Primeau.

As a coach, Conacher was involved in a notable altercation when Detroit Times writer Lew Walter tried to interview him after the Red Wings defeated Chicago 9–2 on February 8, 1950.

Over his three seasons at the helm, Conacher coached the Black Hawks - a team on which his younger brother Roy played - to 6th, 5th and 6th-place finishes respectively, after which he was fired in favor of Ebbie Goodfellow.

Conacher died in 1967 of throat cancer just ten days after his 58th birthday, and was buried in the Mount Pleasant Cemetery, Toronto.
