The spring warm-up is a mixed blessing for millions of Canadians who suffer from seasonal allergies.

Because of long, frigid winter, the sniffling and sneezing, brought on by pollen floating in the air, is expected to start in Ontario later than usual this year, experts say.

To help allergy sufferers prepare for the onslaught, CBC Hamilton is hosting an interactive audio live chat on Monday at noon ET with Dr. Susan Waserman, a professor in the division of clinical immunology in McMaster University's department of medicine. Our host will be reporter Adam Carter (whose allergies include pollen and cats, in case you were wondering).

An allergy expert, Waserman says Ontario may be spared the continent-wide "Pollen Vortex" that some commentators are expecting, but she says the season will come on quickly.

During the live chat, she will answer your questions and give tips on how to minimize the allergy-season misery.

To listen in, visit this page on Monday at noon. You can submit questions for Waserman in advance by emailing hamilton@cbc.ca or by sending a tweet to @cbchamilton.
