What are your goals? In other words, what are you saving for?
That will at least partly define what you should invest in.
If some of the $150k is to make a down payment or buy a house, you would want to keep that money in something safe. Ditto if you plan to go back to school or your emergency fund.
Money that is being saved for longer term goals would probably be best in a low cost index fund such as the Canadian equivalent of Vanguard Total Stock or Vanguard Wellington. Since the markets are a bit frothy at this point, you may be best to value average in over time.
If something cannot endure laughter.... it cannot endure.
Patience is the art of concealing your impatience.
