Super natural BC, with its scenic beauty and mild weather will always be a good investment spot. Add to that Asian immigration into parts of Vancouver and you have a growing province indeed.
However, BC has many mini-markets totally disconnected from each other, with different climatic zones and investment profiles. Investing in Kamloops is different than in Dawson Creek than in Richmond than in downtown Vancouver or Fraser Valley.
The "BC" housing market does not exist, as prices might fall in Vancouver Island as Alberta second home money dries up, might be OK for Vancouver condos and great for newly built houses in Fort St. John.
Understand the city you intend to invest in very very well. Loads of competition in the Lower Mainland where cash-flow does not exist unless you put 50% down, as opposed to cities further north, further out in the Fraser Valley or in the Okanagon.
Be also aware of rent control laws in BC, high degree of unionization, PST issues, land transfer taxes and higher property taxes for non-residents, and in MetroVan access to rapid transit as traffic is horrendous.
