The average housing price in Canada is $659,395 [1], selling Bitcoin using DCA strategy when you don't have enough coins to buy house, is not a wise decision for me.
I suggest you're need to wait until the price surge really high, let's say you think $150K CAD is big, you can sell some portion and hold the rest. People are expecting the highest Bitcoin price in this year halving event will happen in the next year, so you can sell some at the top.

Such method of selling would only be good if you are selling and using it to buy another asset. But selling and keeping the money in CAD fiat is not too a nice idea.
The bitcoin price this time is a significant indication that 150k dollars is possible during the bull run. Why not wait till it hits 100k and you sell like 40% of your portfolio. If it hits 150k, you sell 50% of the remaining portfolio and then leave 10% for the next cycle of DCA.
