Niagara area here. Been doing this about 4 years now. Sean should set up a post primarily for Canadians. There is a difference from the US market and ours. Glad to see some more Canucks on here though. The timing for advertising is a bit of hit & miss. Last year the season was a little later in warming up so late March thru April was pretty good. This year I feel that early to late March was right. I wasn't panning on advertising at all this year as last year I had all the work I could handle (want to stay one man) but I wasn't counting on losing a couple of my good accounts to a new lowballer. So I am hoping to send out fliers "unaddressed admail" by next Tuesday. (BTW I use 20 lb. bond paper & Canada Post delivers them no problem and I've seen regular paper delivered as well...this year costs $0.103 each) In the past I found that door hangers work the best but I don't have the time now as I'm quite busy with clean-ups & aerations. So far this year I've gotten 5 new residential cutting clients just by referrals.
