As Mark said, you'll have to pay both taxes.
I ordered my tail kit last year and it was delivered using FedEX Internationnal Economy(The emp kit is small enough to get shipped using regular courrier). $10 brokerage fees + both taxes and I picked up at the Mirabel airport. Took 3 days!
I ordered my wing kit 2 weeks ago. I was quoted $489 US for shipping using ABF (trucking company) to the Montreal ABF warehouse.
To avoid paying brokerage fees, I'll just drive there, get the papers, go to the import office in Mtl, pay both taxes and get back to ABF. With the tax bill payed, they will give me access to my crates (2). I'll just load them up a in a rented pickup truck or my trailer... and drive home (15min, I'm 25km out of Mtl). I just hope they'll have a fork lift of 2-3 guys to help me out!
If you need any info, send me a MP, I'll give you my phone number! btw, my first language is French (probably your case too).
