We do have statistics on police interactions in respect of marijuana possession as well as charges and convictions.

Clearly police continue to enforce the law - some police forces are more zealous than others.  For example in BC RCMP under contract as local police forces seem to be more strict that their BC municipal counterparts.  In fact Kelowna BC policed by the RCMP leads the way.

As reported:

"According to 2014 data from Statistics Canada, 77 per cent of the time Saskatoon police stop someone suspected of having pot, they lay a charge.That compares with 48 per cent in Regina . The Canadian average was 39 per cent.

Meanwhile, if you look at the per capita rates of pot charges, Saskatoon ranks fourth behind Kelowna, Gatineau and Sherbrooke."
