No KEH equivalent in Canada. Prices, new or used, WILL be higher, sometimes laughingly so, than from US and selection more limited. With CDN $$ so close to US, I'd suggest having your friends order gear you want from US for delivery to them and you pay them when you arrive. You'll get what you want faster and far cheaper. KEH or B&H out of NYC are reliable, fast and have a good selection.
- NO DUTIES on lenses or cameras, only modest vat (no more than 13%). Same tax would be paid if bought IN Canada.
- Avoid shipping UPS if can as they charge a $%^& 'brokerage fee' not charged by USPS. However, if must ship UPS (e.g. KEH) , chose World Wide Saver or Premium/Priority (can't recall actual name) higher-end service as no brokerage fee. UPS or Fedex will have to Toronto with days, USPS Global Priority, etc can take a week or so.
CDN market is just too small for good used gear selections and prices, unless a private sale, are almost always much higher than from US - new or used. I almost always buy my gear from US as 99.99% of time is significantly cheaper after shipping.
