It's hats off to the heat. It was too hot for bearskins yesterday; especially after the march from Queen's Park to Nathan Phillips Square. the order stand at ease was followed to the letter by members of the Royal Regiment of Canada. Off came the busbies. The regiment was one of more than 15 units taking part in garrison services to mark Dominion Day Week observances in Metro. About 2;000 members of the Canadian Forces in full ceremonial dress took part. Temperature was steamy 28C (83F)
