Hi,
The housing market generally in Canada at the moment is slowing.
However the self build market is increasing, I have 8 acres in Mont Tremblant and have plans to build a cabin with a big garden, purchase value of the land (only) was GBP 29500 it has now been valued at GBP 52000 that's over two years.
The one to watch is Nova Scotia the bras d' or lake network (Luxembourg and lunenberg counties) huge gains on land parcels, have purchased three lakeside plots, all making very very strong gains. Finally look out for a small place called Covey Lake disgustingly big profits being made around there at the moment and extremley beautiful. The typical Canadian dream and all that!
New Brunswick and Nova Scotia have a HST (Harmonised Sales Tax) circulates at around 15% so factor this in
Hope this helps
Any further help feel free, Quebec & NS are more my area though
Cheers
