This tiny church is called a procession chapel. 
Pilgrims walking in procession to the Basilica Ste. Anne De Beaupre just outside Quebec City for healing or worship could stop at little proceession chapels along the way to pray.
This one was built in memory of Joseph- Masse Gravel who came to Quebec from France in 1641. The inscription says the chapel was built by Joseph’s son. 
You enter the tiny chapel through this beautifully decorated door. 
You can pray and light a candle at the shrine inside. 
Your prayers can be written in the book on the chapel window sill. 
The procession chapel is a beautiful place to pray for any pilgrim on life’s journey.
